N-(2,5-Dichlorophenyl)-2-((4-ethyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 577765-20-9

Description

CATO supplies N-(2,5-Dichlorophenyl)-2-((4-ethyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 577765-20-9), a certified reference material (molecular formula C17H15Cl2N5OS, MW 408.30 g/mol) for analytical method development and quality control.

The molecular framework of N-(2,5-Dichlorophenyl)-2-((4-ethyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C17H15Cl2N5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
