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 (4-Hydroxyphenyl)triphenylphosphonium.
(4-Hydroxyphenyl)triphenylphosphonium (CAS 22883-70-1), molecular formula C24H20OPBr and molecular weight 435.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Hydroxyphenyl)triphenylphosphonium (C24H20OPBr) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (4-Hydroxyphenyl)triphenylphosphonium 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.
