TETRA-N-HEXYLAMMONIUM BROMIDE

white to faintly yellow powder

Tetrahexylammonium bromide can be used:

• As a hydrogen bond acceptor in the preparation of deep eutectic solvents which can be used for desulfurization and denitrogenation from n-heptane.
• To produce aqueous biphasic system for the heavy metal ions preconcentration.
• As a phase transfer salt to fabricate an optical chemical gas-sensor.

The utilization of ion-pairing reagents as mobile phase additives allows the elution of ionic and highly polar substances using reversed phase HPLC columns. The purity of mobile phase additives is a prime factor to their successful application. Sigma-Aldrich offers an outstanding collection of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) analyzes. All mobile phase additives are rigorously tested with special emphasis on the requirements of modern reversed phase HPLC:

Wash the bromide with ether, and dry it in a vacuum at room temperature for 3 days.
