Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(3-Cyclopropyl-4-(difluoromethyl)-6-(4-ethylphenyl)-1h-pyrazolo[3,4-b]pyridin-1-yl)acetic acid (CAS 937607-29-9) is a high-purity analytical reference standard with the molecular formula C20H19F2N3O2 and a molecular weight of 371.38 g/mol.
2-(3-Cyclopropyl-4-(difluoromethyl)-6-(4-ethylphenyl)-1h-pyrazolo[3,4-b]pyridin-1-yl)acetic acid (C20H19F2N3O2) contains a steroid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-(3-Cyclopropyl-4-(difluoromethyl)-6-(4-ethylphenyl)-1h-pyrazolo[3,4-b]pyridin-1-yl)acetic 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.
