Metizolam (Cas 40054-68-0) Usage


Metizolam (also known as desmethyletizolam) is a thienotriazolodiazepine that is the demethylated analogue of the closely related etizolam.

Metizolam is an analytical reference standard categorized as a benzodiazepine. It is a chemical product used primarily as a broad-spectrum fungicide to control fungal diseases in various crops. Metizolam differs structurally from etizolam through removal of the methyl group on the triazole ring.

Metizolam was detectable in hydrolyzed urine during the 46-h period, with concentrations always lower than 11 ng/mL. About 0.3% of the initial dose was excreted in urines as total unchanged metizolam during the first 24 h. The most relevant potential CYP- and UGT-dependent metabolites of metizolam were investigated in vitro using human liver microsome incubation and, subsequently, liquid chromatography coupled with quadrupole-time of flight mass spectrometry (UHPLC-Q-TOF-MS) analysis.
