Description

Methyl 21-Hydroxyheneicosanoate is a high-purity, long-chain fatty acid methyl ester derivative featuring a terminal hydroxyl group. This unique bifunctional structure makes it a valuable intermediate for synthesizing specialized surfactants, lubricants, and polymer precursors. It is particularly sought after by R&D and production teams in the cosmetics, personal care, and specialty chemical industries for creating novel compounds with tailored properties.

Application

• Surfactant & Emulsifier Synthesis: A key building block for producing non-ionic surfactants and emulsifiers used in high-end cosmetic and personal care formulations.
• Lubricant & Grease Additives: Serves as a precursor for synthetic esters that enhance the performance and stability of industrial lubricants and greases.
• Polymer Modification: Used to introduce hydroxyl functionality into polymers, improving adhesion, flexibility, and compatibility in coatings and resins.
• Pharmaceutical Intermediates: Employed in the research and synthesis of bioactive molecules and drug delivery systems due to its long aliphatic chain.
• Specialty Chemical Research: A versatile intermediate in organic synthesis for creating novel compounds in agrochemical and material science research.
