Welabrary, the Welab exclusive 90000 compound chemical library, is structurally diverse, and stock is available for over 95% of the compounds in liquid form and for 78% of them in solid form.

Most compounds have an acceptable planarity disruption and less than 3 aromatic rings and 65% of them show MPO scores above 4, being thus good CNS drug candidates.

Around 20% of the library is annotated with physicochemical, pharmacological and ADMET data, registered in an internal relational database and available for data mining.

The following are some descriptors that characterize the library.
