New MolPort API Calls Help Track Your Orders

Authorized customers are already taking advantage of the MolPort API to programmatically access information from the MolPort database about commercially available compounds, their suppliers, packaging, prices, warehouse inventory information, lead times, and other information. 

MolPort is now pleased to announce the addition of two new MolPort API calls to help customers track their compound orders:

1. List Orders

This API call returns all orders for a specific client, and lists them in descending date order (newest-to-oldest). 
Users submit a GET call to with the client’s MolPort-provided API key, and the API returns:

Count of ordered compounds 
Count of cancelled compounds
Count of compounds already shipped
Count of compounds being processed
MolPort order number
Order date
Order status
Order unique id 

2. Return One Specific Order

This API call returns all the details of a single specified order.

Users submit a GET call to[id] with the client’s MolPort-provided API key, and the API returns:

Order details

Count of ordered compounds
Count of cancelled compounds
Count of compounds already shipped
Count of compounds being processed
MolPort order number
Order date
Order status
Order unique id 

Compound details

Supplier name
Supplier catalogue number
MolPort catalogue number
MolPort reference number
Quantity measure
Invoice number
Promised shipped out date*
Shipped out date

* This value is a subject for change, due to several external reasons, to get reliable & up-to-date information, please make sure to refresh/ make new API call. 

These new API calls are available now and can help you track your orders automatically, by integrating within your system.

Technical details are available in Section 3.3 of the MolPort API documentation, and if you are interested in using the MolPort API, please contact

Is a Compound Worth its Weight in Gold?

What’s the most expensive available, elemental material that you can buy? No, it’s not gold: as of September 7, gold was trading at $62.32 per gram, but lutetium costs $100 per gram, and californium (which has to be made) costs $27M per gram.

What about synthetic organic compounds? Surely, they can’t cost so much, can they? Well actually …. yes, they can. A quick search in MolPort’s comprehensive 7M+ database of available screening compounds and building blocks shows that the most expensive compound on file sells for $3995 per milligram, 64,104 times more expensive than gold on a weight-for-weight basis! Here it is:

Molecular formula: C17H14O7; Molecular weight: 330.292
SMILES: COc1cc2OC3OCCC3(O)c2c2oc(=O)c3C(=O)CCc3c12

Could this be a promising lead? Based on its structural properties, it certainly passes the Pfizer Rule of Five for drug likeness, and a quick search for its InChIKey in PubChem and ChemSpider would show whether it had appeared in any publications. So perhaps it is worth including it in a screening library. 
But can a molecule like this really be worth so much? Maybe. Suppose that it is a key structure needed to complete a crucial structure-activity relationship study that will determine whether a new drug project will continue or be stopped. If the compound is not readily available, the project could be held up while chemists work out how to make it. 

Suppose they work out a synthesis scheme with five steps, each taking a week to complete. That already puts the project back by over a month. And if a single chemist works on the synthesis, even at 50% of their time, that’s 100 hours of work or a cost of $9375 (based on $180K per annum for a fully loaded FTE). 

So maybe that $3995 doesn’t look so bad after all: the project can move ahead quickly, the chemists are freed up to work on other more worthwhile compounds, and the company has saved some $$.

Useful updates- MolPort web tools

Searching in the MolPort database is often the first thing a scientist or researcher does when they want to find available compounds and suppliers. Searchers need quick, simple and intuitive access; they expect to search intelligently by name, structure/substructure/similarity (drawn, SMILES/SMARTS, file) and to filter by building blocks/screening compounds; and they want to understand, explore, and use the hits they get back. 
Because searching is such an important activity, MolPort is continually working to enhance the feature. This ensures that customers can have the fastest and most intuitive experience, and can make quick and immediate use of the search results to refine a hit list or place an order. 
Customer feedback is crucial in improving features and many of our most useful enhancements have come from customer suggestions of tweaks and changes that will make them more efficient and successful. 

We are therefore pleased to announce some valuable customer-suggested changes that will improve compound selection and usability:
1. Molecule Search Results
2. List Search 

1. Changes to Molecule Search Results

After you have run a compound search (via text, (sub)structure, SMILES/SMARTS or file), the hits are displayed in either a list view or a grid view, with a toggle to switch the view:
List and Grid View Toggle
List view
Grid view

In both these views, you can select and deselect compounds, and you can filter on in-stock and made-to-order compounds. You can also save all compounds or your selection to an SDfile.
Previously, you could not transfer hit from the List View direct to List Search. If you wanted to transfer all the compounds or your selection to List Search so that you could generate a quote, use more advanced filters, and place your order, this was only possible by downloading all the results and making the selection and transfer locally on your PC. Customers told us that this was inconvenient and time-consuming, and asked for a fix. 

NEW! Now you can transfer your selected compounds to List Search with one click on “Transfer selected to List Search” and immediately use List Search to make a final selection, estimate price with optimal for the whole list supplier selection, and create a quotation.

2. Changes to List Search

In the previous List Search user interface, customers reported some confusion in the structure display boxes: were they looking at the hit structure (the result of the search), or the query structure (what was searched for)? 
List Search Results Display: was not visible what structure was searched for?
 NEW! To remove this confusion, we have added a “Show Structure Images” checkbox that now displays an image of each searched structure:
Show Structure Images unchecked (Default setting) 
Show Structure Images checked
In addition, if you click on the “Edit” button in the “Status” column, you will see compound images for the relevant suppliers’ catalogs:
Click Edit to see Supplier Catalog Display
NEW: Customers also requested the ability to display and sort on molecular weight in the List Search Results display, and this now appears as a sortable column on the right.

Frequently asked questions

1. What happens if at some point I can't receive my package?

If the recipient can't temporarily receive parcels, that's OK: the packages won’t get stuck in limbo. MolPort can store your orders free of charge for a few weeks if there are issues when we are ready to ship your compounds, such as your logistics facility being closed. Once we get your green light, we’ll ship safely to the destination.

2. What happens to my order if some compounds are delayed in a multiple-compound order? Can the delivery be split or sent as a partial delivery? Are there additional costs for splitting?

MolPort will be tracking the fulfillment of your order, and we will contact you promptly if any supplier cannot make a shipment in the expected time frame. If any part of the order is delayed, we will offer a split shipment at no additional delivery cost.

3. If a supplier is closed, will I still see their compounds in search results?

Their compounds still will be visible in our searches: but the lead time will be an estimate, based on when we think they will open.

4. What will happen to my order if national borders are closed?

For now they are not closed for logistics, and if a supplier can’t ship, we can substitute the supplier, if possible. If a supplier can ship, but MolPort can’t, we would organize drop-shipping. If a supplier can ship but the client can’t receive the shipment, we can hold it in our warehouse. 

5. How should I purchase compounds, in order to receive them in the fastest possible time?

Check the most recent lead time for the supplier. We will update supplier lead times based on the latest information that we receive from them. And read our Blog update for specific supplier details and information.

6. What will happen to my order if I order from a specific supplier, and they can’t ship?

We can switch the suppliers, if the customer is willing to accept any price differences, and if the compound(s) are actually available at different suppliers.

7. What are MolPort doing to stay open and continue operations?  What precautions are MolPort taking and how?

We are following all government and World Health Organization guidelines. 

!!! Please add your question in the comment area, and we will post the answer in the Blog
