Diclazepam (also known as chlorodiazepam) is a lesser-known novel depressant substance of the benzodiazepine class. It is a structural analog of diazepam (Valium) and is reported to produce similar effects.[2]
Diclazepam was first synthesized by Leo Sternbach and his team at Hoffman-La Roche in 1960.
[3] Diclazepam is not currently marketed as a medication, but rather sold online as a research chemical.
