Description

n-Tetradecanoyl-L-Valine CAS NO 14379-30-7 is a high-purity, synthetic amino acid derivative where a myristoyl (C14) fatty acid chain is conjugated to the L-isomer of valine. This molecular design is critical for creating lipophilic peptide conjugates and specialized surfactants with enhanced membrane permeability and stability. It serves as a valuable building block for researchers and manufacturers in the pharmaceutical and cosmetic industries, particularly in the development of novel drug delivery systems and bioactive compounds.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of lipopeptide drugs, prodrugs, and active pharmaceutical ingredients (APIs) requiring improved bioavailability.
• Peptide Modification: Used to introduce lipophilic chains into peptide sequences, enhancing their cell-penetrating ability and metabolic stability for research and therapeutic applications.
• Cosmetic Actives: Serves as a precursor for synthesizing peptide-based cosmetic ingredients that target skin conditioning and anti-aging.
• Biochemical Research: Essential reagent in studying protein-lipid interactions, membrane biochemistry, and the structure-activity relationships of modified amino acids.
• Surfactant & Emulsifier Synthesis: Acts as a raw material for producing specialized, mild surfactants with amino acid backbones for high-end personal care formulations.
