Description

2-Hydroxy-10-Undecenoic Acid Methyl Ester is a versatile bifunctional organic compound featuring both a hydroxyl group and an unsaturated ester moiety. This unique structure makes it a valuable intermediate for synthesizing specialty polymers, lubricants, and fine chemicals. It is particularly sought after by manufacturers in the polymer, cosmetic, and specialty chemical industries for its ability to introduce both reactive sites and long-chain flexibility into final products.

Application

• Polymer Intermediate: Key monomer for the production of specialty polyesters and polyurethanes, imparting flexibility and cross-linking sites.
• Lubricant Additive Synthesis: Used to create bio-based or synthetic ester lubricants with enhanced oxidative stability and low-temperature performance.
• Cosmetic & Personal Care Ingredients: Serves as a precursor for emollients, surfactants, and viscosity modifiers in skin and hair care formulations.
• Pharmaceutical Intermediates: Employed in the synthesis of complex molecules and prodrugs due to its reactive functional groups.
• Surface Coatings & Resins: Acts as a building block for alkyd resins and other coating materials, improving durability and adhesion.
• Flavor & Fragrance Industry: Utilized in the synthesis of macrocyclic musk compounds and other aroma chemicals.
