(4-(Ethoxycarbonyl)benzyl)triphenylphosphonium bromide CAS 75986-31-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-(Ethoxycarbonyl)benzyl)triphenylphosphonium bromide.

(4-(Ethoxycarbonyl)benzyl)triphenylphosphonium bromide (CAS 75986-31-1), molecular formula C28H26O2PBr and molecular weight 505.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4-(Ethoxycarbonyl)benzyl)triphenylphosphonium bromide (C28H26O2PBr) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), (4-(Ethoxycarbonyl)benzyl)triphenylphosphonium bromide 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.
