As a certified reference material (CRM), Tetrabutylphosphonium benzoate 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.
Tetrabutylphosphonium benzoate (CAS 101203-18-3) is a high-purity analytical reference standard with the molecular formula C16H36PC7H5O2 and a molecular weight of 380.55 g/mol.
Tetrabutylphosphonium benzoate (C16H36PC7H5O2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
