Description

1-Octadecyl-5-Oxopyrrolidine-3-Carboxylic Acid is a high-purity, long-chain fatty acid derivative of pyrrolidone carboxylic acid. This specialty chemical serves as a versatile intermediate and functional additive, valued for its unique amphiphilic structure that combines a hydrophobic alkyl chain with a polar heterocyclic head group. It is primarily utilized by manufacturers in the pharmaceutical, personal care, and advanced material sectors for synthesis, formulation, and surface modification applications.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipophilic modification for enhanced bioavailability.
• Personal Care & Cosmetic Formulations: Acts as a skin-conditioning agent, emulsifier, or stabilizer in creams, lotions, and serums due to its surfactant-like properties.
• Polymer & Material Science: Serves as a monomer or functional additive for creating specialty polymers, coatings, and composites with tailored surface characteristics.
• Lubricant & Fuel Additive: Employed as a friction modifier or detergent additive in high-performance lubricants and industrial fluids.
• Research & Development: A key building block in organic synthesis and chemical research for developing new compounds with specific biological or physical properties.
• Surfactant & Detergent Industry: Functions as a precursor or component in the production of specialty surfactants for industrial and institutional cleaning products.
