Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Triphenyl-(3,4,5-trimethoxy-benzyl)-phosphonium,bromide.
Triphenyl-(3,4,5-trimethoxy-benzyl)-phosphonium,bromide (CAS 61240-20-8), molecular formula C28H28O3PBr and molecular weight 523.41 g/mol, is a CATO reference standard with documented purity and traceability.
Triphenyl-(3,4,5-trimethoxy-benzyl)-phosphonium,bromide (C28H28O3PBr) contains a steroid core, a phosphonate group, 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, the carboxyl group imparts weak acidity; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
