Description

Aleuritic Acid is a naturally occurring, long-chain hydroxy fatty acid derived from shellac and other natural sources. This versatile compound serves as a valuable bifunctional building block in organic synthesis, featuring both a carboxylic acid and multiple hydroxyl groups. It is primarily utilized by manufacturers in the cosmetics, pharmaceuticals, and specialty polymer industries for producing esters, polyesters, and other high-value derivatives.

Application

• Cosmetic & Personal Care Ingredients: Used in the synthesis of emollients, wax esters, and surfactants for creams, lotions, and makeup products.
• Pharmaceutical Intermediates: Serves as a key chiral starting material for the synthesis of macrolide antibiotics, prostaglandins, and other bioactive molecules.
• Polymer & Resin Production: Acts as a monomer for creating biodegradable polyesters, alkyd resins, and coatings with enhanced flexibility and adhesion.
• Flavor & Fragrance Industry: Employed in the manufacture of musk analogs and other fragrance compounds due to its specific carbon chain length.
• Chemical Synthesis: A valuable intermediate for producing lactones, diols, and other fine chemicals requiring specific hydroxyl functionality.
• Research & Development: Used in academic and industrial R&D for studying lipid chemistry, polymer science, and natural product synthesis.
