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 4-(2,4-Dimethoxyphenyl)-1-[(4-methoxyphenyl)methyl]-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one (CAS 861206-45-3), a certified reference material (molecular formula C19H21N3O4, MW 355.39 g/mol) for analytical method development and quality control.

4-(2,4-Dimethoxyphenyl)-1-[(4-methoxyphenyl)methyl]-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one (C19H21N3O4) contains a flavonoid core, an amide 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).

As a certified reference material (CRM), 4-(2,4-Dimethoxyphenyl)-1-[(4-methoxyphenyl)methyl]-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one 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.
