4-Methyl-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole-3-thiol CAS 77803-41-9 chemical structure

Description

The occurrence of 4-Methyl-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole-3-thiol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Methyl-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole-3-thiol (CAS 77803-41-9), a certified reference material (molecular formula C12H15N3O3S, MW 281.33 g/mol) for analytical method development and quality control.

The molecular framework of 4-Methyl-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole-3-thiol (C12H15N3O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
