Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate.
Ethyl 1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate (CAS 112055-34-2), molecular formula C13H11F3N2O2 and molecular weight 284.23 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate (C13H11F3N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl 1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate 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.
