Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3,4-Dimethoxybenzyl)triphenylphosphonium Bromide.
(3,4-Dimethoxybenzyl)triphenylphosphonium Bromide (CAS 70219-09-9) is a high-purity analytical reference standard with the molecular formula C27H26O2PBr and a molecular weight of 493.38 g/mol.
The molecular framework of (3,4-Dimethoxybenzyl)triphenylphosphonium Bromide (C27H26O2PBr) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 (3,4-Dimethoxybenzyl)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.
