Description

16-Hydroxyhexadec-9-enoic acid is a long-chain hydroxy fatty acid featuring both a hydroxyl group and a carbon-carbon double bond in its structure. This bifunctional nature makes it a valuable intermediate for synthesizing specialized polymers, surfactants, and bioactive compounds. It is particularly sought after by R&D and production teams in the pharmaceutical, cosmetics, and specialty chemical industries for creating novel materials with tailored properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prostaglandin analogs, lipid-based drug conjugates, and other bioactive molecules.
• Cosmetic Ingredient: Serves as a precursor for emollients, moisturizing agents, and specialty esters in high-end skincare formulations.
• Polymer & Resin Modification: Acts as a monomer or cross-linking agent to introduce flexibility, hydrophilicity, or reactive sites into polyesters, polyurethanes, and alkyd resins.
• Surfactant & Lubricant Synthesis: A key building block for producing non-ionic surfactants, corrosion inhibitors, and bio-based lubricants with enhanced performance.
• Chemical Research (R&D): Employed as a standard or starting material in organic synthesis and metabolic pathway studies.
• Agrochemical Formulations: Used in the development of adjuvants, emulsifiers, and delivery systems for crop protection products.
