Chemical Structure
Description
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.
(R)-(3-Hydroxy-2-methylpropyl)triphenylphosphonium bromide (CAS 73805-15-9), molecular formula C22H24OPBr and molecular weight 415.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-(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 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).
CATO manufactures (R)-(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.
