5-((2,4-Dimethylphenoxy)methyl)-4-phenyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 76151-18-3), molecular formula C17H17N3OS and molecular weight 311.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-((2,4-Dimethylphenoxy)methyl)-4-phenyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (C17H17N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
