3-(Phenoxymethyl)-4,5-di-p-tolyl-4H-1,2,4-triazole (CAS 141078-91-3) is a high-purity analytical reference standard with the molecular formula C23H21N3O and a molecular weight of 355.43 g/mol.
The molecular framework of 3-(Phenoxymethyl)-4,5-di-p-tolyl-4H-1,2,4-triazole (C23H21N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
