Synthesis of Benzoyl Peroxide
Benzoyl chloride is a primary precursor in the industrial synthesis of benzoyl peroxide, a crucial initiator for polymerisation reactions and a common active ingredient in acne treatments.
Dye and Pigment Production
It serves as an intermediate in the manufacturing of various dyes and pigments, contributing to the benzoyl moiety in complex chromophore structures.
Fragrance and Flavour Compounds
Benzoyl chloride is used in the synthesis of esters and other compounds that find application as fragrances and flavouring agents in the cosmetic and food industries.
Pharmaceutical Intermediates
This compound acts as a building block for the synthesis of numerous pharmaceutical active ingredients and intermediates, facilitating the introduction of the benzoyl functional group.
Polymerisation Initiators
Beyond benzoyl peroxide, it is involved in the creation of other organic peroxides that function as initiators in free-radical polymerisation processes.
