Description

n-(2-Hydroxyethyl) Aspartic Acid is a functionalized amino acid derivative that combines the properties of aspartic acid with a hydrophilic hydroxylethyl group. This unique structure makes it a valuable intermediate for synthesizing specialized polymers, surfactants, and chelating agents where enhanced water solubility and biocompatibility are required. It is primarily sought by manufacturers in the personal care, pharmaceutical, and specialty chemical industries for applications ranging from biodegradable chelators to moisturizing agents.

Application

• Chelating Agent Precursor: Used in the synthesis of next-generation, biodegradable chelating agents for detergents, cleaning formulations, and water treatment chemicals.
• Personal Care Ingredients: Serves as a key building block for mild, skin-compatible surfactants and moisturizing agents in cosmetics and skincare products.
• Pharmaceutical Intermediates: Employed in the research and development of prodrugs and active pharmaceutical ingredients (APIs) requiring functionalized amino acid motifs.
• Polymer Modification: Acts as a monomer or cross-linking agent for producing functional polymers with improved hydrophilicity and metal-binding capabilities.
• Biodegradable Surfactants: A starting material for manufacturing environmentally friendly surfactants and dispersants for agricultural and industrial formulations.
• Corrosion Inhibitor Synthesis: Utilized in creating advanced, non-toxic corrosion inhibitors for cooling water systems and metal treatment processes.

Quality Control

Our n-(2-Hydroxyethyl) Aspartic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality.
