Sec-butyltriphenylphosphonium bromide CAS 3968-92-1

Description

Compared with other compounds in its class, the molecular weight of 399.31 g/mol gives Sec-butyltriphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sec-butyltriphenylphosphonium bromide (CAS 3968-92-1), molecular formula C22H24PBr and molecular weight 399.31 g/mol, is a CATO reference standard with documented purity and traceability.

Sec-butyltriphenylphosphonium bromide (C22H24PBr) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Sec-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.
