Methyl undecylenate is a versatile bio-based ester derived from castor oil, primarily used as a precursor in the synthesis of fragrances, polymers, and pharmaceuticals. It is valued for its unique terminal double bond, which allows it to be chemically modified into various high-value derivatives. 🧪 Key Properties
Appearance: Clear, colorless to pale yellow liquid.
Odor: Mild, fatty-green, and slightly fruity; reminiscent of wine.
Chemical Formula: \(C_{12}H_{22}O_2\) (specifically Methyl 10-undecenoate).
Stability: Stable under recommended storage, though it should be kept in cool, dry areas away from light. 🧴 Primary Applications
Cosmetics Personal Care: Acts as a deodorizing agent and fragrance ingredient in deodorants, hair care, and skin care formulations.
Aroma Chemistry: Used to create fruity or "green" top notes in perfumes and flavorings (e.g., wine or brandy accents).
Chemical Synthesis: A critical intermediate for making polyamides (specialty polymers), modified silicones, and antifungal derivatives.
Industrial: Utilized in lubricants, metalworking fluids, and the manufacture of synthetic insect pheromones
