(4-Bromo-2-fluorophenyl)diethylphosphine oxide CAS 2685825-05-0

Description

The occurrence of (4-Bromo-2-fluorophenyl)diethylphosphine oxide is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (4-Bromo-2-fluorophenyl)diethylphosphine oxide (CAS 2685825-05-0), a certified reference material (molecular formula C10H13BrFOP, MW 279.09 g/mol) for analytical method development and quality control.

Structurally, (4-Bromo-2-fluorophenyl)diethylphosphine oxide (C10H13BrFOP) contains organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 279.09 g/mol, it falls into the medium-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), (4-Bromo-2-fluorophenyl)diethylphosphine oxide 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.
