Description

3-Methylundecanal is a high-purity aliphatic aldehyde valued for its unique waxy, citrus-like, and slightly fatty odor profile. This compound is a key building block and fragrance ingredient, prized for its ability to impart complex, long-lasting olfactory characteristics. It is primarily utilized by manufacturers in the flavor and fragrance, cosmetic, and fine chemical synthesis industries seeking to create sophisticated aroma compounds and specialty intermediates.

Application

• Fragrance Formulation: A versatile ingredient in perfumery, used as a heart or base note to add waxy, citrus, and aldehydic nuances to fine fragrances, personal care products, and household cleaners.
• Flavor Enhancement: Employed in trace amounts to create or enhance complex flavor profiles in food and beverage applications, contributing to citrus, fatty, and green notes.
• Cosmetic Ingredients: Serves as a key aromatic component in the formulation of lotions, creams, soaps, and other cosmetic products requiring a stable and distinctive scent.
• Chemical Synthesis: Acts as a crucial intermediate in organic synthesis for the production of more complex fragrance molecules, pharmaceuticals, and specialty chemicals.
• Aroma Chemical Production: Used in the industrial-scale manufacture of other aroma chemicals where its specific carbon chain and functional group are required.
• Functional Fluids & Additives: Potential application in the synthesis of specialty lubricants, plasticizers, or other functional fluid additives.
