Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-2-(4-fluorophenyl)-2H-1,2,3-triazole-4-carboxylic acid.
CATO supplies 5-Bromo-2-(4-fluorophenyl)-2H-1,2,3-triazole-4-carboxylic acid (CAS 1707371-70-7), a certified reference material (molecular formula C9H5BrFN3O2, MW 286.06 g/mol) for analytical method development and quality control.
Structurally, 5-Bromo-2-(4-fluorophenyl)-2H-1,2,3-triazole-4-carboxylic acid (C9H5BrFN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 286.06 g/mol, it falls into the medium-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.
As a certified reference material (CRM), 5-Bromo-2-(4-fluorophenyl)-2H-1,2,3-triazole-4-carboxylic acid 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.
