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 3,5-Dimethyl-1-(p-tolyl)-1H-pyrazole-4-carboxylic acid (CAS 108444-21-9), a certified reference material (molecular formula C13H14N2O2, MW 230.26 g/mol) for analytical method development and quality control.
3,5-Dimethyl-1-(p-tolyl)-1H-pyrazole-4-carboxylic acid (C13H14N2O2) contains a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 3,5-Dimethyl-1-(p-tolyl)-1H-pyrazole-4-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.
