Chemical Structure
Description
Structurally, 8-Chloro-3-(chlorodifluoromethyl)-6-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyridine (C8H2Cl2F5N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 306.02 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 8-Chloro-3-(chlorodifluoromethyl)-6-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 478248-86-1), a certified reference material (molecular formula C8H2Cl2F5N3, MW 306.02 g/mol) for analytical method development and quality control.
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.
