Currently the library contains about 440 000 natural and synthetic screening compounds and over 12 000 natural and synthetic building blocks. The information in the database includes logP, H-bond donors, H-bond acceptors, rotable bonds. All compounds are subject to strict quality control, including on Bruker NMR spectrometer and/or Finnigan mass spectrometer. The majority of our compounds will have a purity of >95% and should all have a purity >92%. Compounds are supplied as dry powder in any fixed mg or umole amounts in the range of 1 to 100 mg.
