Chemical Structure

Dibromotriphenylphosphine CAS 1034-39-5 chemical structure

Description

As a certified reference material (CRM), Dibromotriphenylphosphine 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.

Dibromotriphenylphosphine (CAS 1034-39-5), molecular formula C18H33Br2P and molecular weight 440.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Dibromotriphenylphosphine (C18H33Br2P) is characterized by organophosphorus functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
