Description and Uses

Benzoin is used as a flavor, antiseptic and photopolymerization catalyst. It is also used as a raw material in organic syntheses. It serves as a precursor to benzil, which is a photoinitiator. Further, it is used as degassing agent for powder coatings. In addition to this, it is used as an additive and in powder coating to remove the pinhole phenomenon.
