When completely hydrolyzed, it yields two molecules of glucose and one each of benzaldehyde and hydrocyanic acid.
The latter in turn breaks down at into benzaldehyde and HCN.
On account of the readiness with which it condenses with various compounds, benzaldehyde is an important synthetic reagent.
Chlorine and nitric acid oxidize it to benzil; chromic acid mixture and potassium permanganate, to benzoic acid and benzaldehyde.
Emulsine has the property of being able to hydrolyse the glucoside amygdalin to glucose, benzaldehyde, and hydrocyanic acid.
It crystallizes from water in large rhombic crystals, which melt at 118 C. Oxidizing agents convert it into benzaldehyde.
