Chemical Structure
Description
(4-Methoxy-3-nitrobenzyl)triphenylphosphonium bromide (C26H23NO3PBr) contains a steroid core, an amide group, 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).
(4-Methoxy-3-nitrobenzyl)triphenylphosphonium bromide (CAS 313673-23-3) is a high-purity analytical reference standard with the molecular formula C26H23NO3PBr and a molecular weight of 508.35 g/mol.
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.
