3-(Difluoromethyl)-5-((3-fluorobenzyl)thio)-4H-1,2,4-triazole CAS 1706441-62-4

Description

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.

3-(Difluoromethyl)-5-((3-fluorobenzyl)thio)-4H-1,2,4-triazole (CAS 1706441-62-4), molecular formula C10H8F3N3S and molecular weight 259.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 3-(Difluoromethyl)-5-((3-fluorobenzyl)thio)-4H-1,2,4-triazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
