Benzoin is not a constituent of benzoin resin obtained from the benzoin tree (Styrax) or tincture of benzoin. The main component in these natural products is benzoic acid.
Benzoin was first synthesized in 1832 by Justus von Liebig and Friedrich Woehler during the research on bitter almond oil, which was benzaldehyde with traces of hydrocyanic acid. The catalytic synthesis by the benzoin condensation was improved by the research of Nikolay Zinin during his time with Liebig.
