Ethyl 5-bromo-1-(4-fluorophenyl)-1H-pyrazole-4-carboxylate CAS 1082828-31-6

Description

Ethyl 5-bromo-1-(4-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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Ethyl 5-bromo-1-(4-fluorophenyl)-1H-pyrazole-4-carboxylate (CAS 1082828-31-6) is a high-purity analytical reference standard with the molecular formula C12H10BrFN2O2 and a molecular weight of 313.12 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Ethyl 5-bromo-1-(4-fluorophenyl)-1H-pyrazole-4-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
