Description

11-Hydroxyundecanoic Acid is a versatile bifunctional organic compound featuring both a terminal hydroxyl group and a carboxylic acid group on a long aliphatic chain. This unique structure makes it a valuable intermediate for the synthesis of specialty polymers, plasticizers, and high-performance lubricants. It is particularly sought after by manufacturers in the polymer, pharmaceutical, and fine chemical industries for producing polyesters, polyamides, and other functional materials.

Application

• Polymer Intermediate: A key monomer for the production of bio-based polyesters and polyamides (nylon-11 precursors).
• Plasticizer Synthesis: Used in the manufacture of ester-based plasticizers for PVC and other polymers.
• Lubricant Additive: Serves as a precursor for synthetic esters used in high-performance lubricants and greases.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs.
• Cosmetic Ingredients: Used to synthesize emollients, surfactants, and viscosity modifiers.
• Fine Chemical Building Block: A versatile starting material for organic synthesis, including chain extension and functionalization reactions.
• Adhesive & Coating Resins: Incorporated into formulations for improved flexibility and adhesion.
