Tetrabutylphosphoniumtoluene-4-sulfonate (CAS 116237-97-9), molecular formula C16H36PC7H7O3S and molecular weight 430.63 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tetrabutylphosphoniumtoluene-4-sulfonate (C16H36PC7H7O3S) contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 430.63 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Tetrabutylphosphoniumtoluene-4-sulfonate 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.
