Beschreibung

Allgemeine Beschreibung

1-Bromobutane, an organobromine compound, is a commonly used industrial solvent for cleaning, extraction and chemical synthesis.

Anwendung

1-Bromobutane may be used as a derivatization reagent for multiple functional groups (amino, carboxyl, and phenolic hydroxyl groups) of amino acids to improve hydrophobicities and basicities of the amino acids. It may also be used as an internal standard for the quantification of 1- and 2-bromopropane in human urine by headspace gas chromatography.
