Description

n-Hexadecanoyl-L-Alanine is a high-purity, synthetic amino acid derivative where palmitic acid is conjugated to the L-isomer of alanine. This molecular design is critical for applications requiring precise chirality and defined lipophilicity, offering superior consistency and performance over racemic mixtures. It serves as a key intermediate and functional ingredient for advanced research and manufacturing in the pharmaceutical, cosmetic, and specialty chemical sectors, where material purity and structural integrity are paramount.

Application

• Pharmaceutical Intermediate: Used in the synthesis of peptide-based drugs, prodrugs, and active pharmaceutical ingredients (APIs) requiring lipophilic modification for enhanced bioavailability.
• Cosmetic & Personal Care Actives: Functions as a skin-conditioning agent and emulsifier in premium formulations such as anti-aging creams, serums, and moisturizers.
• Biochemical Research: Employed as a substrate or building block in enzymatic studies, metabolic pathway research, and the development of novel biochemical probes.
• Surfactant & Emulsifier Synthesis: Acts as a precursor for the production of specialized, mild surfactants with amide linkages for industrial and consumer product applications.
• Nutraceutical Formulations: Incorporated into advanced delivery systems for nutritional supplements to improve the stability and absorption of active compounds.
