CAS 100-52-7C7H6O106.12 g/mol

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.

Physical and chemical properties
Melting Point	-15 °F (NTP, 1992)
Boiling Point	354 °F at 760 mmHg (NTP, 1992)
Density	1.046 at 68 °F (USCG, 1999) - Denser than water; will sink
Solubility	less than 0.1 mg/mL at 67.1 °F (NTP, 1992)
Flash Point	148 °F (NTP, 1992)
Vapor Pressure	1 mmHg at 79.2 °F ; 5 mmHg at 122.2 °F; 10 mmHg at 144 °F (NTP, 1992)
Appearance	Benzaldehyde appears as a clear colorless to yellow liquid with a bitter almond odor. Flash point near 145 °F. More denser than water and insoluble in water. Hence sinks in water. Vapors are heavier than air. The primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways. Used in flavoring and perfume making.
