What is Benzaldehyde?

Benzaldehyde is an arenecarbaldehyde that consists of benzene bearing a single formyl substituent; the simplest aromatic aldehyde and parent of the class of benzaldehydes. It has a role as a flavouring agent, a fragrance, an odorant receptor agonist, an EC 3.1.1.3 (triacylglycerol lipase) inhibitor, a plant metabolite and an EC 3.5.5.1 (nitrilase) inhibitor.
