Description
Isovaleraldehyde (CAS 590-86-3) is a short-chain aliphatic aldehyde commercially identified under the names Isovaleral, Isopentanal, and FEMA 2692. It carries no E-code designation and is classified within the Flavors and Fragrances category. Its molecular formula is C5H10O, and it is also abbreviated as iso-C4H9CHO in technical literature.
In food and beverage formulation, isovaleraldehyde contributes malty, cocoa, and apple-like top notes at concentrations typically in the low ppm range, functioning through its reactive carbonyl group to interact with other flavor precursors during processing. In personal care applications, it serves as a fragrance intermediate, providing diffusive lift to floral and green accords in finished compositions.
Isovaleraldehyde is supplied as a liquid meeting FCC-grade specifications for food-contact applications and is subject to REACH registration requirements for supply within the EU. It is classified under HS code 29121900. Procurement quantities are available in drum and IBC formats from compliant European distributors.
