Chemical Structure
Description
5-(Difluoromethyl)-3-methyl-1h-1,2,4-triazole (CAS 1094760-03-8), molecular formula C4H5F2N3 and molecular weight 133.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine substitution, 5-(Difluoromethyl)-3-methyl-1h-1,2,4-triazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
CATO manufactures 5-(Difluoromethyl)-3-methyl-1h-1,2,4-triazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
