Chemical Structure
Description
1-(4-(Thiophen-2-yl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (CAS 955963-41-4), molecular formula C12H6F3N3O2S2 and molecular weight 345.32 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-(Thiophen-2-yl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (C12H6F3N3O2S2) 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, 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.
