Description

N-(3,5-Bis(trifluoromethyl)phenyl)-2-((4-ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 556802-21-2), molecular formula C18H14F6N4OS2 and molecular weight 480.45 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(3,5-Bis(trifluoromethyl)phenyl)-2-((4-ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C18H14F6N4OS2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 N-(3,5-Bis(trifluoromethyl)phenyl)-2-((4-ethyl-5-(thiophen-2-yl)-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.
