Benzoin (organic compound)

Benzoin was first reported in 1832 by Justus von Liebig and Friedrich Woehler during their research on oil of bitter almond, which is benzaldehyde with traces of hydrocyanic acid.

[2] The catalytic synthesis by the benzoin condensation was improved by Nikolay Zinin during his time with Liebig.

[5][6] The conversion proceeds by organic oxidation using copper(II),[7] nitric acid, or oxone.

[8] Benzoin also sees wide spread use in powder coating formulations, where it acts as a degassing agent during the curing stage.

[9][10] Benzoin can be used in the preparation of several pharmaceutical drugs including oxaprozin, ditazole, and phenytoin.

NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
