Description

L-Aspartic Acid, n-Dodecyl-, 4-Dodecyl Ester is a specialized long-chain alkyl ester derivative of the amino acid L-aspartic acid. This compound is valued for its unique amphiphilic properties, combining a polar amino acid head with non-polar lauryl (dodecyl) chains, making it a versatile intermediate for advanced synthesis. It is primarily sought by R&D chemists and process engineers in the life sciences, specialty chemical, and advanced material sectors for applications requiring tailored surface activity or specific molecular architecture.

Application

• Surfactant & Emulsifier Intermediate: Serves as a key building block for synthesizing novel, biodegradable non-ionic or amphoteric surfactants with potential use in personal care and industrial formulations.
• Pharmaceutical & Cosmetic Ingredient Synthesis: Used in the research and development of prodrugs, lipid conjugates, or active delivery systems that benefit from enhanced lipophilicity and membrane permeability.
• Polymer & Material Science: Acts as a functional monomer or modifier for creating polymers with specific interfacial properties, such as coatings, adhesives, or compatibilizers.
• Lubricant & Fuel Additive Precursor: Investigated for developing novel ashless additives that can provide detergency, anti-wear, or corrosion inhibition properties.
• Bioconjugation & Biochemical Research: Utilized as a chemical tool for attaching hydrophobic labels or tags to peptides, proteins, or other biomolecules in research settings.
• Catalyst & Ligand Development: Explored in organometallic chemistry for creating chiral ligands or phase-transfer catalysts due to its structured chiral center and long alkyl chains.

Quality Control

Our production of L-Aspartic Acid, n-Dodecyl-, 4-Dodecyl Ester adheres to strict quality management protocols. Each batch is characterized using advanced analytical techniques including HPLC, GC, NMR, and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, chiral purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture uptake and potential degradation.
