As a certified reference material (CRM), 4-(4-Isopropylphenyl)-5-methyl-2-(3-(trifluoromethyl)benzyl)-2,4-dihydro-3H-1,2,4-triazol-3-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.
CATO supplies 4-(4-Isopropylphenyl)-5-methyl-2-(3-(trifluoromethyl)benzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 860785-32-6), a certified reference material (molecular formula C20H20F3N3O, MW 375.39 g/mol) for analytical method development and quality control.
Structurally, 4-(4-Isopropylphenyl)-5-methyl-2-(3-(trifluoromethyl)benzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (C20H20F3N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 375.39 g/mol, it falls into the moderately-high-molecular-weight range. 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.
