Description

L-Aspartic Acid, n-(1,2-Dicarboxyethyl)- is a specialized derivative of aspartic acid, featuring an additional dicarboxyethyl moiety that enhances its chelating and metal-binding properties. This structural modification makes it a valuable intermediate for synthesizing complex peptides, metal complexes, and specialty chemicals where precise molecular architecture is required. It is primarily sought by research institutions and manufacturers in the pharmaceutical, biochemical research, and advanced material science sectors for developing novel compounds and formulations.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized peptides, prodrugs, and active pharmaceutical ingredients (APIs) requiring specific chelating functionalities.
• Biochemical Research: Serves as a key reagent or building block in studying enzyme mechanisms, metal-protein interactions, and metabolic pathways.
• Chelating Agent Synthesis: Acts as a precursor for developing novel, biodegradable chelating agents used in water treatment, agriculture, and industrial cleaning formulations.
• Advanced Material Science: Employed in the preparation of functional polymers, metal-organic frameworks (MOFs), and coatings where its dicarboxylate groups can coordinate with metal ions.
• Cosmetic & Personal Care: Potential use in formulating skin-care products where amino acid derivatives are valued for their moisturizing and skin-conditioning properties.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and industrial use. While specific grades (e.g., Pharmaceutical, Reagent) can be supplied, all batches are characterized to confirm identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, chiral purity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
