Looking for molecules similar to the one you already know? Our Molport Similarity Search tool makes it simple to explore related compounds and expand your options.
Begin by identifying your molecule using SMILES, CAS Number, Molport ID, or other unique identifiers. From the molecule’s page, just one click launches a search for similar structures—ready for you to filter, review, and refine.
Prefer a hands-on approach? You can also draw your own structure, convert identifiers, set your similarity index, and run the search directly from the navigation bar.
From there, easily download your results in SDF format, explore marketplace offers, or send your selection straight to List Search to check availability, get instant quotes, and place orders.
