Quality Control

Our D-Alanine, 3-[(S)-(Phenylmethyl)Sulfinyl]- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high chemical and chiral purity, meeting the stringent requirements for research and synthesis. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are available upon request.

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 tightly sealed after opening to prevent degradation from atmospheric moisture.
