Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Amino-1-benzyl-N-(3,4-difluorophenyl)-1H-1,2,3-triazole-4-carboxamide (CAS 900013-33-4), a certified reference material (molecular formula C16H13F2N5O, MW 329.30 g/mol) for analytical method development and quality control.
The molecular framework of 5-Amino-1-benzyl-N-(3,4-difluorophenyl)-1H-1,2,3-triazole-4-carboxamide (C16H13F2N5O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
