Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Methyl-1-(3-trifluoromethyl-phenyl)-1H-thieno[2,3-c]pyrazole-5-carboxylic acid (CAS 721415-89-0), a certified reference material (molecular formula C14H9F3N2O2S, MW 326.29 g/mol) for analytical method development and quality control.
3-Methyl-1-(3-trifluoromethyl-phenyl)-1H-thieno[2,3-c]pyrazole-5-carboxylic acid (C14H9F3N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
CATO manufactures 3-Methyl-1-(3-trifluoromethyl-phenyl)-1H-thieno[2,3-c]pyrazole-5-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
