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 1-benzyl-3-thien-2-yl-1H-pyrazole-4-carboxylic acid (CAS 956411-88-4), a certified reference material (molecular formula C15H12N2O2S, MW 284.33 g/mol) for analytical method development and quality control.
1-benzyl-3-thien-2-yl-1H-pyrazole-4-carboxylic acid (C15H12N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 1-benzyl-3-thien-2-yl-1H-pyrazole-4-carboxylic acid 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.
