2-((4-(2,4-Dimethylphenyl)-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)thio)-N-(2-methoxybenzyl)acetamide CAS 872211-49-9

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.

CATO supplies 2-((4-(2,4-Dimethylphenyl)-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)thio)-N-(2-methoxybenzyl)acetamide (CAS 872211-49-9), a certified reference material (molecular formula C27H25N5O3S, MW 499.58 g/mol) for analytical method development and quality control.

The molecular framework of 2-((4-(2,4-Dimethylphenyl)-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)thio)-N-(2-methoxybenzyl)acetamide (C27H25N5O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).

As a certified reference material (CRM), 2-((4-(2,4-Dimethylphenyl)-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)thio)-N-(2-methoxybenzyl)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.
