The Clonazepam, with the CAS registry number 1622-61-3, is also known as 5-(2-Chlorophenyl)-7-nitro-3H-1,4-benzodiazepin-2(1H)-one. It belongs to the product categories of Organics;Intermediates & Fine&Chemicals;Pharmaceuticals;Amines;Aromatics;Heterocycles.This chemical's molecular formula is C₁₅H₁₀ClN₃O₃ and molecular weight is 315.71.Its EINECS number is 216-596-2. What's more,Its systematic name is Clonazepam. It is an anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of Gamma-aminobutyric acid receptor responses.
