Back in 2015, we launched the Chemspace project with just 15 million molecules. At that time, we had the largest catalog available on the market. And we never stopped expanding!

Now our catalog comprises 11.5 BILLION molecules. We are endlessly proud that Chemspace remains the largest online platform for small and large molecules searchable and purchasable online: building blocks, screening compounds, intermediates, fragments, reagents, consumables, peptides, proteins, and antibodies.

We also support API connection to our database, as well as the different types of integrations (Punchout and standalone site, catalog upload, etc.)

Thank you for staying with us during this interesting and challenging journey!
