Description

2-Methyl-2-(2-Propenyl)Undecanal is a high-purity aliphatic aldehyde with a unique, powerful, and diffusive green-floral odor profile. This compound matters as a key fragrance intermediate and building block for creating complex, long-lasting scent accords in fine perfumery. It is primarily needed by manufacturers in the flavor and fragrance industry, as well as by research and development chemists specializing in aroma chemical synthesis.

Application

• Fragrance Ingredient: A versatile building block for creating green, floral, and aldehydic top notes in fine perfumes, personal care products, and household detergents.
• Aroma Chemical Synthesis: Serves as a crucial intermediate in the synthesis of more complex fragrance molecules and specialty aroma chemicals.
• Flavor Modifier: Used in trace amounts to enhance or modify flavor profiles in certain high-value food and beverage applications.
• Research & Development: Employed in organic synthesis and chemical research for studying the properties and reactions of branched-chain aldehydes.
• Functional Fluids & Additives: Potential use as an intermediate in the production of specialty lubricants, plasticizers, or other functional chemical additives.
