Chemical Structure
Description
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.
[(2-aminophenyl)methyl]triphenylphosphanium bromide (CAS 78133-84-3) is a high-purity analytical reference standard with the molecular formula C25H23NPBr and a molecular weight of 448.34 g/mol.
[(2-aminophenyl)methyl]triphenylphosphanium bromide (C25H23NPBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
