Benzaldehyde

CAS: 100-52-7

Overview

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 that underpins its commercial value across flavor, fragrance, and synthesis markets.

In industry, it functions as a key intermediate for pharmaceutical synthesis, a flavoring agent, and a reactive building block for polymer and fine chemical production. In food and beverage manufacturing, it is used to impart almond, cherry, and marzipan flavor profiles.

These applications are common in confectionery, baked goods, and liqueurs. Pharmaceutical producers rely on it as a synthetic intermediate for active ingredients including ampicillin and other semi-synthetic penicillins. It is a vital component in modern medicine production.

In polymer chemistry, it acts as a monomer or chain-transfer agent in certain resin and coating formulations. Personal care formulators incorporate it into perfume compounds and functional fragrance blends where a sharp, almond-floral note is required for the final product.

Benzaldehyde is supplied as a clear liquid in drum, IBC, and bulk quantities. 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 available as a distinct commercial grade. This specific grade commands a premium in flavor and fragrance markets due to its natural origin and high purity standards for consumers.
