Pinazepam: analytical study of synthesis, degradation, potential impurities.

Pinazepam specifications are presented, synthesis method and quality control in the course of the synthesis on the starting materials, intermediate products and solvents are described. The used analytical methods of studied potential impurities, both from the synthesis and from degradation under exceptional conditions, are summarized and their validation is done. At last the Pinazepam satisfactory big stability is shown.
