CATO supplies Methyl 4-chloro-2-(trifluoromethyl)thieno[3,4-b]pyridine-7-carboxylate (CAS 175203-40-4), a certified reference material (molecular formula C10H5ClF3NO2S, MW 295.67 g/mol) for analytical method development and quality control.
Methyl 4-chloro-2-(trifluoromethyl)thieno[3,4-b]pyridine-7-carboxylate (C10H5ClF3NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
