N-(2-Cyano-3-methylbutan-2-yl)-2-((4-(2,4-difluorophenyl)-5-phenyl-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 745068-65-9

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.

N-(2-Cyano-3-methylbutan-2-yl)-2-((4-(2,4-difluorophenyl)-5-phenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 745068-65-9), molecular formula C22H21F2N5OS and molecular weight 441.50 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2-Cyano-3-methylbutan-2-yl)-2-((4-(2,4-difluorophenyl)-5-phenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (C22H21F2N5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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 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).

CATO manufactures N-(2-Cyano-3-methylbutan-2-yl)-2-((4-(2,4-difluorophenyl)-5-phenyl-4H-1,2,4-triazol-3-yl)thio)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.
