Chemical Structure
Description
1-(difluoromethyl)-5-ethynyl-triazole (CAS 2845318-71-8), molecular formula C5H3F2N3 and molecular weight 143.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(difluoromethyl)-5-ethynyl-triazole (C5H3F2N3) contains a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 143.09 g/mol, it falls into the low-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).
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 1-(difluoromethyl)-5-ethynyl-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.
