Description

12-Acetyloxystearic Acid is a versatile fatty acid derivative, specifically an acetylated hydroxy stearic acid, with the CAS registry number 1069-92-7. This compound is valued for its bifunctional nature, combining a carboxylic acid group with an acetyl-protected hydroxyl group, which makes it a valuable intermediate for chemical synthesis. It is primarily sought after by manufacturers in the chemical, pharmaceutical, and specialty materials sectors for the production of lubricants, plasticizers, and advanced polymer precursors.

Application

• Chemical Intermediate: A key building block for synthesizing complex esters, amides, and other derivatives used in specialty chemicals.
• Lubricant & Grease Additive: Used in the formulation of synthetic lubricants and metalworking fluids to enhance performance characteristics.
• Polymer Modification: Serves as a monomer or modifier in the production of polyesters, alkyd resins, and other polymers to alter flexibility and hydrophobicity.
• Plasticizer Precursor: Employed in the manufacture of ester-based plasticizers for PVC and other plastics.
• Pharmaceutical Intermediates: Utilized in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs due to its metabolically labile acetyl group.
• Cosmetic & Personal Care Ingredients: Acts as an intermediate for emulsifiers and texture-enhancing agents in formulations.
• Surface Coatings: Incorporated into coatings and inks to improve adhesion and film properties.
• Research & Development: Used in academic and industrial R&D for exploring new materials and synthetic pathways.
