Quality Control

Our n-(n-Acetyl-L-Alanyl)-L-Alanine Butyl Ester is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral analysis to confirm stereochemical integrity, ensuring compliance with research and development standards. Certificates of Analysis (COA) detailing identity, purity, and specific impurities 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 place at a controlled room temperature (typically 15-25°C). This material may be hygroscopic (moisture-sensitive); therefore, the container should be kept tightly sealed in a dry environment.
