Quality Control

Our (2R,3R)-Butanediol Bis(Methanesulfonate), 97% is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the specified grade and consistent performance for critical applications. Certificates of Analysis (COA) documenting identity, purity (HPLC/GC), and chiral excess are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture.
