Description and Uses
Butyryl chloride is used as an intermediate for the synthesis of active pharmaceutical ingredients benzoyl peroxide, t-butyl perbenzoate, and benzophenone. It is also used as an acylation reagent. Further, it is used in the preparation of peroxides such as benzoyl peroxide, benzophenone and t-butyl perbenzoate. In addition to this, it is involved in the preparation of chromones and antiproliferative agents.
Butyryl chloride has been used to esterify wood meal dissolved in the ionic liquid, 1-butyl-3-methylimidazolium chloride.
