2-((4-(2,4-Dimethylphenyl)-5-(2-hydroxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-nitrophenyl)acetamide CAS 831193-02-3

Description

CATO supplies 2-((4-(2,4-Dimethylphenyl)-5-(2-hydroxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-nitrophenyl)acetamide (CAS 831193-02-3), a certified reference material (molecular formula C24H21N5O4S, MW 475.52 g/mol) for analytical method development and quality control.

2-((4-(2,4-Dimethylphenyl)-5-(2-hydroxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-nitrophenyl)acetamide (C24H21N5O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 2-((4-(2,4-Dimethylphenyl)-5-(2-hydroxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-nitrophenyl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
