Description

8-Methyl-7-Nonenal is a high-value, unsaturated aliphatic aldehyde with a distinctive, powerful green, citrus, and waxy odor profile. This compound matters as a key fragrance and flavor intermediate, prized for its ability to impart fresh, natural, and complex olfactory notes to formulations. It is primarily needed by manufacturers in the flavor and fragrance (F&F) industry, as well as by producers of fine chemicals and aroma chemicals for personal care, cosmetics, and household products.

Application

• Fragrance Ingredient: A key building block for creating fresh, green, and citrusy top notes in perfumes, colognes, and fine fragrances.
• Flavor Modifier: Used to enhance and round off citrus, melon, and tropical fruit flavor profiles in food and beverage applications.
• Aroma Chemical Synthesis: Serves as a crucial intermediate in the synthesis of more complex aroma molecules and specialty aldehydes.
• Personal Care Products: Incorporated into soaps, shampoos, lotions, and deodorants to provide a fresh, clean scent character.
• Household & Industrial Products: Used in air fresheners, detergents, and cleaning agents to deliver a pleasant, uplifting fragrance.
• Cosmetic Formulations: Adds desirable olfactory characteristics to creams, gels, and other cosmetic preparations.
