Decanal dimethyl acetal

Decanal dimethyl acetal (CAS 7779-41-1), also known as 1,1-Dimethoxydecane, FEMA 2363, and NSC 46132, is an acetal compound formed by the condensation of decanal with methanol. It carries the EC number 231-928-6 and is recognised under the FEMA flavour ingredient registry, making it identifiable across fragrance and flavour documentation.

In food and beverage formulation, it functions as a flavouring agent, releasing decanal slowly under acidic conditions to deliver a controlled fatty, citrus-peel character with improved stability over the free aldehyde. In personal care applications, it contributes aldehydic top notes to fragrance compositions while offering reduced reactivity compared to its parent aldehyde, which benefits formulation longevity.

Decanal dimethyl acetal is supplied as an oil-phase liquid and is available in flavour-grade quality aligned with FEMA and REACH compliance requirements. Procurement teams should confirm lot-specific documentation including CoA and SDS. Packaging formats typically follow standard chemical drum and IBC configurations.
