title: Hydrolysis of clonazepam, flunitrazepam and nitrazepam by hydrochloric acid. Identification of some additional products.
abstract: Several by-products in the hydrochloric acid hydrolysis of clonazepam, flunitrazepam and nitrazepam are isolated by a combination of TLC and HPLC. With mass and NMR spectroscopic methods the structures of the by-products are established. Some indications are given for possible modes of formation of the by-products.
