Chemical Structure

2-(Benzylthio)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one CAS 51646-33-4 chemical structure

Description

CATO supplies 2-(Benzylthio)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one (CAS 51646-33-4), a certified reference material (molecular formula C13H12N4OS, MW 272.33 g/mol) for analytical method development and quality control.

The molecular framework of 2-(Benzylthio)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one (C13H12N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 2-(Benzylthio)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one 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.
