2-((4-Amino-5-(4-chlorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(3,5-dimethoxyphenyl)acetamide CAS 568548-60-7

Description

2-((4-Amino-5-(4-chlorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(3,5-dimethoxyphenyl)acetamide (CAS 568548-60-7), molecular formula C18H18ClN5O3S and molecular weight 419.89 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((4-Amino-5-(4-chlorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(3,5-dimethoxyphenyl)acetamide (C18H18ClN5O3S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-((4-Amino-5-(4-chlorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(3,5-dimethoxyphenyl)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.
