Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 283.23 g/mol gives Tetrapropylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetrapropylphosphonium bromide (CAS 63462-98-6), molecular formula C12H28PBr and molecular weight 283.23 g/mol, is a CATO reference standard with documented purity and traceability.
Tetrapropylphosphonium bromide (C12H28PBr) contains 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. 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 Tetrapropylphosphonium 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.
