Description

Cinnamaldehyde Diethyl Acetal CAS NO 7148-78-9 is a versatile aromatic acetal derivative of cinnamaldehyde, valued for its unique organoleptic properties and chemical reactivity. This compound serves as a key intermediate and specialty ingredient, offering a more stable and less pungent alternative to its parent aldehyde. It is primarily sought after by manufacturers in the flavor and fragrance, pharmaceutical, and fine chemical synthesis industries for its ability to impart warm, spicy, balsamic notes and participate in protected carbonyl chemistry.

Application

• Flavor & Fragrance Industry: Used as a modifying agent and base note in perfumery, and as a flavoring agent for creating cinnamon, spicy, and balsamic profiles in food and beverages.
• Pharmaceutical Intermediates: Serves as a protected aldehyde synthon in the multi-step synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Organic Synthesis: Acts as a versatile building block in Grignard reactions, nucleophilic additions, and other transformations where a masked carbonyl group is required.
• Specialty Chemicals: Employed in the formulation of agrochemicals, dyes, and other performance chemicals where its aromatic structure is beneficial.
• Research & Development: Utilized in academic and industrial R&D laboratories for method development and novel compound discovery.
