Tetra-n-butylammonium phosphate, 99+%

Description

Used as a counter-ion in ion-pair chromatography of water-soluble vitamins | CAS: 5574-97-0 | C16H38NO4P | 339.46 g/mol

Tetra-n-butylammonium phosphate is used as a counter-ion in ion-pair reagent in high-performance liquid chromatography for the simultaneous determination of chlorpheniramine and maleate of water-soluble vitamins. It acts as a phase transfer catalyst. Further, it is used as a buffering reagent in HPLC. In addition to this, it is used as a mobile phase additive in two-dimensional reversed-phase high-performance thin-layer chromatography for the separation of chenodeoxycholic acid and deoxycholic acid.
