Tangible
Building Blocks

For more than 15 years, UORSY have been acquiring an ultimate knowledge of synthetic organic chemistry. This has allowed us to create a pool of
15 000 000 synthetically accessible chemical building blocks.

Screening Compounds

In-stock library comprises more than 600 000 compounds. More than 85% of our collection has drug-like physicochemical profiles, and more than 35% – satisfy lead-like requirements.
