4,5-Bis-trifluoromethyl-pyridin-2-ylamine (CAS 176762-33-7), molecular formula C7H4F6N2 and molecular weight 230.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,5-Bis-trifluoromethyl-pyridin-2-ylamine (C7H4F6N2) is characterized by a nitrile group, 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
