Application

Tetrabutylammonium iodide may be used as a mobile phase additive in ion-pair high-performance liquid chromatography (IP-HPLC) assay of 4-aminopyridine in serum. Tetrabutylammonium iodide may also be used as a mobile phase additive in the analysis of tetracycline by reversed-phase IPC. The addition of tetrabutylammonium iodide regulates the retention of tetracyclines.

General description

Tetrabutylammonium iodide is an ion-pair chromatography (IPC) reagent suitable for anionic separation sorted by carbon chain length.

Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions of tetrabutylammonium 2-pyridyltriolborate salts with various aryl (heteroaryl) chlorides can produce the corresponding desired coupling products with good to excellent yields. These tetrabutylammonium salts are more reactive than the corresponding lithium salts. The coupling reactions with
