Description

n-Undecanol is a versatile, long-chain primary fatty alcohol with the CAS number 112-42-5, prized for its role as a key intermediate in the synthesis of high-value fine chemicals. Its linear structure and terminal hydroxyl group make it an essential building block for creating plasticizers, surfactants, and fragrance components with specific performance characteristics. This chemical is particularly valuable for manufacturers in the flavors & fragrances, polymer, and specialty chemical industries seeking to develop products with tailored properties.

Application

• Fragrance and Flavor Ingredient: Used as a raw material in the synthesis of esters and other aroma chemicals, contributing to fruity, waxy, or citrus notes in perfumes and food flavorings.
• Plasticizer Intermediate: Serves as a precursor for producing esters like diundecyl phthalate, which are used as specialty plasticizers to improve the flexibility and durability of polymers such as PVC.
• Surfactant and Detergent Manufacturing: Acts as a hydrophobic feedstock for the production of nonionic surfactants (e.g., ethoxylates) and lubricant additives, enhancing wetting, emulsification, and cleaning properties.
• Pharmaceutical and Cosmetic Intermediates: Utilized in the synthesis of active pharmaceutical ingredients (APIs) and emollients for personal care formulations, valued for its purity and predictable reactivity.
• Lubricant and Corrosion Inhibitor Additive: Incorporated into synthetic lubricants and metalworking fluids to modify viscosity and provide protective film-forming characteristics.
• Chemical Research and Development: Employed as a standard or reagent in organic synthesis and material science research for creating novel compounds and polymers.
