(S)-(3-Hydroxy-2-methylpropyl)triphenylphosphonium bromide CAS 81658-46-0

Description

Compared with other compounds in its class, the molecular weight of 415.31 g/mol gives (S)-(3-Hydroxy-2-methylpropyl)triphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-(3-Hydroxy-2-methylpropyl)triphenylphosphonium bromide (CAS 81658-46-0), a certified reference material (molecular formula C22H24OPBr, MW 415.31 g/mol) for analytical method development and quality control.

The molecular framework of (S)-(3-Hydroxy-2-methylpropyl)triphenylphosphonium bromide (C22H24OPBr) 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.

CATO manufactures (S)-(3-Hydroxy-2-methylpropyl)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.
