N-(3-Chloro-4-methoxyphenyl)-2-((4-ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 566880-27-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3-Chloro-4-methoxyphenyl)-2-((4-ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide.

CATO supplies N-(3-Chloro-4-methoxyphenyl)-2-((4-ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 566880-27-1), a certified reference material (molecular formula C17H17ClN4O2S2, MW 408.93 g/mol) for analytical method development and quality control.

N-(3-Chloro-4-methoxyphenyl)-2-((4-ethyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C17H17ClN4O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
