1-[(4-Methoxyphenyl)methyl]-3-methyl-4-(4-phenoxyphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one CAS 860789-23-7

Description

1-[(4-Methoxyphenyl)methyl]-3-methyl-4-(4-phenoxyphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one (C23H21N3O3) contains a steroid 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).

1-[(4-Methoxyphenyl)methyl]-3-methyl-4-(4-phenoxyphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one (CAS 860789-23-7), molecular formula C23H21N3O3 and molecular weight 387.43 g/mol, is a CATO reference standard with documented purity and traceability.

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), 1-[(4-Methoxyphenyl)methyl]-3-methyl-4-(4-phenoxyphenyl)-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.
