What is Benzaldehyde?
Benzaldehyde (CAS 100-52-7), also known as benzoic aldehyde, is the simplest aromatic aldehyde and a primary aroma chemical recognized under FEMA 2127; it delivers the characteristic bitter almond scent.
Where is Benzaldehyde used?
- Pharmaceutical synthesis: key intermediate for active ingredients including ampicillin and other semi-synthetic penicillins
- Food and beverage: flavoring agent imparting almond, cherry, and marzipan profiles in confectionery, baked goods, and liqueurs
- Polymer chemistry: monomer or chain-transfer agent in resin and coating formulations
- Personal care: perfume compounds and functional fragrance blends with a sharp, almond-floral note
- It also serves as a reactive building block for fine chemical production.
Good to know: Food-grade material meeting FCC specifications is standard for flavor applications, while technical-grade product serves industrial synthesis and polymer uses. Natural benzaldehyde, derived from bitter almond or stone fruit processing, is a distinct commercial grade commanding a premium in flavor and fragrance markets.
Commercial specifications
- Clear liquid in drum, IBC, and bulk quantities
- Natural grade: derived from bitter almond or stone fruit processing, high purity
