Description

Lauric Anhydride CAS NO 645-66-9 is a high-purity organic chemical intermediate, specifically the symmetrical anhydride of lauric acid. This compound is valued for its role as a versatile acylating agent and building block in the synthesis of more complex molecules. It is essential for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to produce esters, amides, and other derivatives with a C12 alkyl chain.

Application

• Pharmaceutical Intermediates: Acylating agent in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs.
• Agrochemical Synthesis: Key building block for manufacturing herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Modification: Used to introduce hydrophobic lauroyl groups into polymers to alter physical properties like flexibility and moisture resistance.
• Lubricant & Grease Additives: Intermediate in the production of specialty esters that enhance lubricity and thermal stability.
• Cosmetic & Personal Care Ingredients: Serves as a precursor for emollients, surfactants, and viscosity modifiers.
• Flavor & Fragrance Compounds: Used in the synthesis of esters that contribute to specific aromatic profiles.
• Organic Synthesis & Research: A reliable reagent for introducing the dodecanoyl moiety in academic and industrial R&D laboratories.
