Description

Oleic Aldehyde Dimethyl Acetal is a high-purity chemical intermediate, also known as 9-Octadecenal dimethyl acetal. This compound serves as a versatile and protected aldehyde synthon, offering enhanced stability for synthetic transformations compared to its parent aldehyde. It is primarily utilized by manufacturers in the fragrance, flavor, and pharmaceutical industries for the synthesis of complex organic molecules, where precise control over functional groups is essential.

Application

• Fragrance & Flavor Synthesis: A key building block for creating aldehydic, waxy, and citrus notes in high-value perfumes and flavor compositions.
• Pharmaceutical Intermediates: Used in the multi-step synthesis of active pharmaceutical ingredients (APIs) and other bioactive compounds.
• Organic Synthesis & Research: Acts as a protected form of oleic aldehyde (9-octadecenal) in academic and industrial research laboratories for Grignard reactions, nucleophilic additions, and other critical transformations.
• Specialty Chemicals: Employed in the production of surfactants, lubricant additives, and other oleochemical derivatives requiring specific chain length and functionality.
• Agrochemical Intermediates: Serves as a precursor in the development of certain pesticides and plant growth regulators.
