Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Oxo-4-phenylbutyl)triphenylphosphonium bromide.
CATO supplies (4-Oxo-4-phenylbutyl)triphenylphosphonium bromide (CAS 89490-63-1), a certified reference material (molecular formula C28H26OPCl, MW 444.94 g/mol) for analytical method development and quality control.
The molecular framework of (4-Oxo-4-phenylbutyl)triphenylphosphonium bromide (C28H26OPCl) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (4-Oxo-4-phenylbutyl)triphenylphosphonium bromide 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.
