Chemical Structure
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.
CATO supplies 5-(difluoromethyl)-3-ethyl-1H-1,2,4-triazole (CAS 1247413-25-7), a certified reference material (molecular formula C5H7F2N3, MW 147.13 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine substitution, 5-(difluoromethyl)-3-ethyl-1H-1,2,4-triazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.13 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).
As a certified reference material (CRM), 5-(difluoromethyl)-3-ethyl-1H-1,2,4-triazole 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.
