Clonazolam is a drug of the benzodiazepine class. Benzodiazepine medicines have a benzene ring fused to a diazepine ring, which is a seven membered ring with the two nitrogen constituents located at R1 as well as R4. The benzyl ring of clonazolam is replaced at R8 with a nitro group, NO2-. Additionally, the diazepine ring is bound at R6 to a 2-chlorinated phenyl ring.
Clonazolam likewise consists of a 1-methylated triazole ring fused to as well as including R1 and R2 of its diazepine ring. Clonazolam belongs to a class of benzodiazepines containing this integrated triazole ring, called triazolobenzodiazepines, distinguished by the suffix “-zolam.” Clonazolam is additionally a nitrobenzodiazepine, a subdivision of benzodiazepines which consist of a nitro (NO2-) group. Other nitrobenzodiazepines include clonazepam and flunitrazepam.
