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-(3,5-Dimethylphenyl)-5-phenyl-4,5-dihydro-1h-pyrazole-3-carboxylic acid (CAS 1264043-98-2), a certified reference material (molecular formula C18H18N2O2, MW 294.35 g/mol) for analytical method development and quality control.
1-(3,5-Dimethylphenyl)-5-phenyl-4,5-dihydro-1h-pyrazole-3-carboxylic acid (C18H18N2O2) contains a steroid core, an amide 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.
CATO manufactures 1-(3,5-Dimethylphenyl)-5-phenyl-4,5-dihydro-1h-pyrazole-3-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.
