Description

Octadecyl L-Tyrosinate is a high-purity, long-chain amino acid ester derivative synthesized from L-tyrosine. This compound is valued for its amphiphilic properties, which make it a versatile building block for advanced formulations and research. It is primarily utilized in the pharmaceutical, cosmetic, and specialty chemical industries for applications requiring biocompatible surfactants, lipid conjugates, or peptide mimetics. Our supply ensures consistent quality and reliable availability for global industrial and research needs.

Application

• Pharmaceutical Intermediates: Used as a key synthon in the development of prodrugs, peptide derivatives, and lipid-based drug delivery systems to enhance bioavailability.
• Cosmetic & Personal Care Ingredients: Functions as a gentle, skin-compatible emulsifier or conditioning agent in high-end skincare and haircare formulations.
• Biochemical Research: Serves as a substrate or standard in enzymatic studies, membrane research, and the investigation of lipid-protein interactions.
• Specialty Surfactants: Acts as a non-ionic or cationic surfactant component in niche industrial applications requiring biodegradability and low toxicity.
• Material Science: Employed in the surface functionalization of nanoparticles and the creation of self-assembled monolayers (SAMs) for biomedical devices.
