Description
Compared with other compounds in its class, the molecular weight of 312.27 g/mol gives 1-Phenyl-3-(trifluoromethyl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Phenyl-3-(trifluoromethyl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid (CAS 887360-86-3), a certified reference material (molecular formula C13H7F3N2O2S, MW 312.27 g/mol) for analytical method development and quality control.
1-Phenyl-3-(trifluoromethyl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid (C13H7F3N2O2S) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Phenyl-3-(trifluoromethyl)-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.
