Chemical Structure
Description
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.
CATO supplies 2-Methyl-5-(trifluoromethyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-ol (CAS 95095-67-3), a certified reference material (molecular formula C7H5F3N4O, MW 218.14 g/mol) for analytical method development and quality control.
The molecular framework of 2-Methyl-5-(trifluoromethyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-ol (C7H5F3N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
