Description

7-Methyl-2-Octenal is a high-purity, unsaturated aliphatic aldehyde with a distinctive, powerful green and citrus-like odor profile. This compound matters as a key fragrance and flavor intermediate, prized for its ability to impart fresh, natural, and waxy nuances to complex formulations. It is primarily needed by manufacturers in the flavor and fragrance (F&F) industry, as well as by research and development chemists exploring novel organic syntheses.

Application

• Fragrance Compound: A crucial building block for creating fresh, green, and citrus top notes in fine perfumery, personal care products, and air fresheners.
• Flavor Ingredient: Used to enhance and replicate natural green, waxy, and citrus flavors in food and beverage applications.
• Aroma Chemical Synthesis: Serves as a versatile intermediate in the synthesis of more complex aroma molecules and specialty chemicals.
• Research & Development: Utilized in academic and industrial R&D for studying organic reactions, particularly those involving α,β-unsaturated aldehydes.
• Functional Fluids & Additives: Potential use as a precursor or intermediate in the production of specialty lubricants and polymer additives.
