Dichlorophenyl phosphine oxide CAS 824-72-6

Description

The occurrence of Dichlorophenyl phosphine oxide is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dichlorophenyl phosphine oxide (CAS 824-72-6), molecular formula C6H5Cl2OP and molecular weight 194.98 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dichlorophenyl phosphine oxide (C6H5Cl2OP) contains organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine 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 194.98 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).

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), Dichlorophenyl phosphine 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.
