Chemical Structure

Bis(2-dichlorophosphinophenyl) ether CAS 1293994-89-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bis(2-dichlorophosphinophenyl) ether.

Bis(2-dichlorophosphinophenyl) ether (CAS 1293994-89-4), molecular formula C12H8Cl4OP2 and molecular weight 371.95 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Bis(2-dichlorophosphinophenyl) ether (C12H8Cl4OP2) contains organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 371.95 g/mol, it falls into the moderately-high-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.

CATO manufactures Bis(2-dichlorophosphinophenyl) ether under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
