Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 567.64 g/mol gives Hexadecyltriphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Hexadecyltriphenylphosphonium bromide (CAS 14866-43-4), molecular formula C34H48PBr and molecular weight 567.64 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Hexadecyltriphenylphosphonium bromide (C34H48PBr) contains organophosphorus functionality, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 567.64 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
