Chemical Structure

n-Butyltriphenylphosphonium Bromide CAS 1779-51-7 chemical structure

Description

n-Butyltriphenylphosphonium Bromide (CAS 1779-51-7) is a high-purity analytical reference standard with the molecular formula C22H24PBr and a molecular weight of 399.31 g/mol.

Structurally, n-Butyltriphenylphosphonium Bromide (C22H24PBr) 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 399.31 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).

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.

CATO manufactures n-Butyltriphenylphosphonium Bromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
