Quality Control

Our D-Alanine, n-[(1S)-1-Carboxyethyl]-, Rel- (9Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure identity, strength, and composition. Certificates of Analysis (COA) documenting all test results are available for every shipment to support your regulatory and R&D requirements.

Storage

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