Tetrabutylphosphoniumbutylsulfate CAS 654057-99-5

Description

The occurrence of Tetrabutylphosphoniumbutylsulfate is closely related to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tetrabutylphosphoniumbutylsulfate (CAS 654057-99-5) is a high-purity analytical reference standard with the molecular formula C16H36PC4H9O4S and a molecular weight of 412.61 g/mol.

Structurally, Tetrabutylphosphoniumbutylsulfate (C16H36PC4H9O4S) contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 412.61 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.

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), Tetrabutylphosphoniumbutylsulfate 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.
