Description
As a certified reference material (CRM), 2-Chloro-6-methyl-4-(4-(trifluoromethyl)phenyl)pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-Chloro-6-methyl-4-(4-(trifluoromethyl)phenyl)pyridine (CAS 697739-23-4), a certified reference material (molecular formula C13H9ClF3N, MW 271.67 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 2-Chloro-6-methyl-4-(4-(trifluoromethyl)phenyl)pyridine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 271.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
