Chemical Structure
Description
Structurally, 2-Bromo-5-fluorobenzoyl chloride (C7H3BrClFO) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 237.45 g/mol, it falls into the medium-molecular-weight range. 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).
2-Bromo-5-fluorobenzoyl chloride (CAS 111771-13-2) is a high-purity analytical reference standard with the molecular formula C7H3BrClFO and a molecular weight of 237.45 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), 2-Bromo-5-fluorobenzoyl chloride 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.
