Description

Compared with other compounds in its class, the molecular weight of 313.12 g/mol gives Ethyl 1-(4-bromophenyl)-5-fluoro-1H-pyrazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 1-(4-bromophenyl)-5-fluoro-1H-pyrazole-4-carboxylate (CAS 1269293-78-8), a certified reference material (molecular formula C12H10BrFN2O2, MW 313.12 g/mol) for analytical method development and quality control.

Structurally, Ethyl 1-(4-bromophenyl)-5-fluoro-1H-pyrazole-4-carboxylate (C12H10BrFN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 313.12 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 1-(4-bromophenyl)-5-fluoro-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.
