Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Triphenyl(3,7,11-trimethyldodeca-2,6,10-trien-1-yl)phosphonium bromide.
Triphenyl(3,7,11-trimethyldodeca-2,6,10-trien-1-yl)phosphonium bromide (CAS 75499-95-5) is a high-purity analytical reference standard with the molecular formula C33H40PBr and a molecular weight of 547.56 g/mol.
Triphenyl(3,7,11-trimethyldodeca-2,6,10-trien-1-yl)phosphonium bromide (C33H40PBr) contains organophosphorus functionality, bromine substitution, a polycyclic aromatic system. 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
