Chemical Structure
Description
Pentan-2-yltriphenylphosphonium bromide (C23H26PBr) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Pentan-2-yltriphenylphosphonium bromide (CAS 17827-53-1) is a high-purity analytical reference standard with the molecular formula C23H26PBr and a molecular weight of 413.34 g/mol.
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.
As a certified reference material (CRM), Pentan-2-yltriphenylphosphonium bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
