The occurrence of (4-Bromophenyl)phosphinic acid is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (4-Bromophenyl)phosphinic acid (CAS 39238-95-4), a certified reference material (molecular formula C6H6BrO2P, MW 220.99 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H6BrO2P, (4-Bromophenyl)phosphinic acid contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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), (4-Bromophenyl)phosphinic acid 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.
