Description

Hydroxyasparticacid CAS NO 90625-36-8 is a non-proteinogenic amino acid derivative characterized by the presence of both hydroxyl and carboxylic acid functional groups. This unique structure makes it a valuable chiral building block and intermediate for synthesizing more complex bioactive molecules. It is primarily utilized by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications in drug discovery and fine chemical synthesis.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of novel active pharmaceutical ingredients (APIs), particularly for compounds targeting neurological and metabolic pathways.
• Peptide Synthesis: Used as a modified amino acid residue to introduce hydroxyl functionality into synthetic peptides, altering their solubility, stability, and biological activity.
• Biochemical Research: Employed as a standard or reagent in enzymatic studies and metabolic pathway analysis due to its role as an aspartic acid analog.
• Agrochemical Synthesis: Acts as a precursor in the manufacture of certain herbicides and plant growth regulators that require specific chiral centers for efficacy.
• Chelating Agent Precursor: Its multifunctional structure allows for the development of novel chelating agents for metal ion sequestration in industrial processes.
• Cosmetic Ingredient Synthesis: Utilized in the production of certain moisturizing and anti-aging compounds designed to mimic natural skin factors.

Quality Control

Our Hydroxyasparticacid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, enantiomeric purity, and impurity profiles. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates.

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 nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
