(2-Bromo-4-chlorophenyl)dimethylphosphine oxide CAS 2759950-99-5

Description

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

(2-Bromo-4-chlorophenyl)dimethylphosphine oxide (CAS 2759950-99-5), molecular formula C8H9BrClOP and molecular weight 267.49 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, (2-Bromo-4-chlorophenyl)dimethylphosphine oxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (2-Bromo-4-chlorophenyl)dimethylphosphine 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.
