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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
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.
Solubility
Soluble in chlorine. Slightly soluble in water, ethanol and ether.
Notes
Moisture sensitive. Incompatible with acids, acid anhydrides, acid chlorides and strong oxidizing agents.
