Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Chloro-3-(4-chlorophenyl)-6-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyridine.
8-Chloro-3-(4-chlorophenyl)-6-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 338795-19-0), molecular formula C13H6Cl2F3N3 and molecular weight 332.11 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H6Cl2F3N3, 8-Chloro-3-(4-chlorophenyl)-6-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 332.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
