benzaldehyde (C6H5CHO), the simplest representative of the aromatic aldehydes[1], occurring naturally as the glycoside[2] amygdalin[3]. Prepared synthetically, it is used chiefly in the manufacture of dyes[4], cinnamic acid, and other organic compounds[5], and to some extent in perfumes[6] and flavouring[7] agents.

Benzaldehyde was first isolated in 1803, and in the 1830s the German chemists Justus von Liebig[8] and Friedrich Wöhler[9] investigated the compound[10] in studies that laid the foundation for the structural theory of organic chemistry[11]. Industrially, benzaldehyde is made by a process in which toluene[12] is treated with chlorine[13] to form benzal chloride, followed by treatment of benzal chloride with water[14].

Benzaldehyde is readily oxidized to benzoic acid[15] and is converted to addition products by hydrocyanic acid or sodium bisulfite. It undergoe...
