The occurrence of (2-Hydroxy-5-methylphenyl)triphenylphosphonium bromide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2-Hydroxy-5-methylphenyl)triphenylphosphonium bromide (CAS 2005487-65-8), a certified reference material (molecular formula C25H22OPBr, MW 449.33 g/mol) for analytical method development and quality control.
(2-Hydroxy-5-methylphenyl)triphenylphosphonium bromide (C25H22OPBr) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 (2-Hydroxy-5-methylphenyl)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.
