Description
Aspartic Acid is a non-essential, acidic amino acid that serves as a fundamental building block in both biological systems and industrial synthesis. Its versatile chemical structure, featuring two carboxyl groups, makes it a critical intermediate for producing a wide range of high-value compounds. This product is essential for manufacturers in the pharmaceutical, food and beverage, and biodegradable polymer industries seeking reliable, high-purity raw materials.
Application
- Pharmaceutical Intermediates: A key chiral building block for the synthesis of active pharmaceutical ingredients (APIs), including certain antibiotics and sweeteners.
- Food & Beverage Additives: Used in the production of Aspartame, a high-intensity artificial sweetener, and as a flavor enhancer (umami) in its L-form.
- Biodegradable Polymers: Serves as a monomer for the synthesis of polyaspartic acid, a biodegradable polymer used in water treatment, scale inhibition, and superabsorbent materials.
- Nutritional Supplements: Incorporated into animal feed and human nutritional supplements for its role in metabolism and the urea cycle.
- Cosmetic Ingredients: Utilized in skincare formulations for its moisturizing and antioxidant properties.
- Chelating Agents: Acts as a precursor for environmentally friendly chelating agents used in detergents and cleaning products.
- Chemical Synthesis: Employed in organic synthesis for introducing chiral centers and carboxylic acid functionalities.

Quality Control
Our Aspartic Acid is manufactured under a strict quality management system. We offer various grades, including Food Grade (FCC), Pharmaceutical Grade (USP/EP), and Technical Grade, to meet diverse application requirements. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral purity assessment. Certificates of Analysis (COA) are provided to ensure traceability and compliance with your specifications.
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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
