Description

(Z)-3,7-Dimethylocta-2,6-Dienal CAS NO 106-26-3 is a high-purity, naturally occurring terpenoid aldehyde, widely recognized as the primary constituent of lemongrass oil. This compound is valued for its intense, fresh, and citrus-like aroma, making it a cornerstone ingredient in the flavor and fragrance industry. It is essential for manufacturers in perfumery, cosmetics, and food flavoring who require consistent quality and authentic natural character in their formulations.

Application

• Fragrance & Perfumery: A key top-note ingredient in fine fragrances, soaps, detergents, and personal care products for its powerful, fresh, lemony scent.
• Flavoring Agent: Used to impart a natural citrus flavor in food products, beverages, confectionery, and oral care items like toothpaste and mouthwash.
• Aromatherapy & Essential Oils: Serves as a primary component in lemongrass essential oil blends used for therapeutic and wellness applications.
• Cosmetic Formulations: Incorporated into lotions, creams, and skincare products for its aromatic properties and potential soothing effects.
• Household Products: Utilized as a deodorizing and freshening agent in air fresheners, cleaning products, and insecticides.
• Chemical Synthesis: Acts as a valuable chiral intermediate and starting material in the synthesis of vitamins (e.g., Vitamin A), ionones, and other fine chemicals.
