Flubromazepam Chemical Properties, Uses, Production

Uses

Flubromazepam is a designer benzodiazepine drug structurally related to Phenazepam ; a drug used in the treatment of neurological disorders such as epilepsy, alcohol withdrawal and insomnia. Phenazepam can also be used as a premedication before surgery as it augments the effects of anesthetics and reduces anxiety.
Flubromazepam is a potent, long-acting novel psychoactive benzodiazepine with anxiolytic, anticonvulsant, muscle relaxant and hypnotic properties. Flubromazepam reportedly has a high addiction potential and risk of overdose. This certified Snap-N-Spike® solution is suitable for use as a starting material in calibrators and controls for numerous GC/MS or LC/MS applications in forensic analysis, clinical toxicology and urine drug testing.

Description

Flubromazepam (Item No. 15157) is an analytical reference standard categorized as a benzodiazepine. Flubromazepam has been detected in seized samples and has anxiolytic and sedative properties. This product is intended for research and forensic applications.

Uses

Flubromazepam is a designer benzodiazepine drug structurally related to Phenazepam (P295300); a drug used in the treatment of neurological disorders such as epilepsy, alcohol withdrawal and insomnia. Phenazepam (P295300) can also be used as a premedication before surgery as it augments the effects of anesthetics and reduces anxiety.
