Methyl {[5-(4-methylphenyl)-4-phenyl-4H-1,2,4-triazol-3-yl]thio}acetate CAS 332911-18-9

Description

CATO supplies Methyl {[5-(4-methylphenyl)-4-phenyl-4H-1,2,4-triazol-3-yl]thio}acetate (CAS 332911-18-9), a certified reference material (molecular formula C18H17N3O2S, MW 339.41 g/mol) for analytical method development and quality control.

The molecular framework of Methyl {[5-(4-methylphenyl)-4-phenyl-4H-1,2,4-triazol-3-yl]thio}acetate (C18H17N3O2S) is characterized by a steroid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Methyl {[5-(4-methylphenyl)-4-phenyl-4H-1,2,4-triazol-3-yl]thio}acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
