Description
Propionaldehyde (CAS 123-38-6, EC 204-623-0), also known as propanal, propional, or FEMA 2923, is a short-chain aliphatic aldehyde belonging to the flavors and fragrances category. It carries no assigned E-code and is classified under HS code 29121900 for customs and trade purposes.
In food and beverage formulation, propionaldehyde functions as a flavorant by contributing sharp, fruity top notes at low concentrations, where its high reactivity with other flavor precursors drives the development of complex aroma profiles. In personal care and cosmetics, it serves as a fragrance intermediate, reacting with amines and alcohols to build aldehyde-forward scent accords.
Propionaldehyde is supplied in food-grade quality meeting FCC specifications and is subject to REACH registration requirements within the European market. It is available in standard industrial drum and IBC packaging formats, with documentation including SDS and certificate of analysis provided upon request.
