Quality Control

Our Disodium (R*,S*)-Tartrate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay, chiral purity, and impurity profiles are available upon request. We can support compliance with relevant pharmacopeial standards (e.g., USP, EP) for specific grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture.
