Description

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.

2-((4-Amino-5-(3-chlorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-methoxy-5-methylphenyl)acetamide (CAS 763108-71-0), molecular formula C18H18ClN5O2S and molecular weight 403.89 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((4-Amino-5-(3-chlorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-methoxy-5-methylphenyl)acetamide (C18H18ClN5O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).

CATO manufactures 2-((4-Amino-5-(3-chlorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-methoxy-5-methylphenyl)acetamide 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.
