Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 313.12 g/mol gives Ethyl 5-bromo-1-(2-fluorophenyl)-1H-pyrazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 5-bromo-1-(2-fluorophenyl)-1H-pyrazole-4-carboxylate (CAS 1245101-35-2) is a high-purity analytical reference standard with the molecular formula C12H10BrFN2O2 and a molecular weight of 313.12 g/mol.
Ethyl 5-bromo-1-(2-fluorophenyl)-1H-pyrazole-4-carboxylate (C12H10BrFN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 5-bromo-1-(2-fluorophenyl)-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.
