Purity & Quality
Minimal purity of Screening Collection compounds is 90%. Average purity ~ 95%. All structures have been confirmed by NMR and MASS spectra and passed computer-assisted professional expertise. We guarantee absolute correspondence of our chemicals to the given chemical structures.
Diversity & Originality This collection is quite original both by its content and pricing. The selection of compounds is based on their non-occurrence in other collections and chemical originality of the structure.
