Description

11-Hydroxyundecyl Acetate is a high-purity, long-chain fatty alcohol ester with significant utility as a versatile chemical intermediate. Its bifunctional structure, featuring both a terminal hydroxyl group and an acetate ester, makes it a valuable building block for synthesizing more complex molecules in fine chemical and pharmaceutical manufacturing. This compound is particularly relevant for producers of specialty polymers, lubricant additives, and cosmetic ingredients who require consistent quality and reliable supply chains.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the production of active pharmaceutical ingredients (APIs) and prodrugs, leveraging its modifiable functional groups.
• Polymer & Resin Modification: Used as a monomer or plasticizer precursor to impart flexibility, hydrophobicity, or specific release properties to polymers.
• Lubricant & Grease Additive: Acts as a precursor for synthetic esters that enhance the thermal stability and lubricity of industrial and automotive lubricants.
• Cosmetic & Personal Care Ingredient: Employed in the synthesis of emollients, surfactants, and viscosity modifiers for creams, lotions, and other formulations.
• Fragrance & Flavor Synthesis: Functions as an intermediate for creating macrocyclic musks and other long-chain aroma chemicals.
• Surface Coating Agent: Utilized in the production of coatings and inks to improve adhesion, flow, and durability.
