4-(2,6-Difluorophenyl)-5-methyl-2-(4-nitrobenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one CAS 861206-33-9

Description

Structurally, 4-(2,6-Difluorophenyl)-5-methyl-2-(4-nitrobenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (C16H12F2N4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 346.29 g/mol, it falls into the moderately-high-molecular-weight range. 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).

4-(2,6-Difluorophenyl)-5-methyl-2-(4-nitrobenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 861206-33-9), molecular formula C16H12F2N4O3 and molecular weight 346.29 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
