Quality Control

Our Dl-1,4-Dichloro-2,3-Butanediol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available for every shipment. We are committed to meeting the stringent requirements of research and industrial applications.

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 moisture absorption. Keep away from incompatible materials such as strong bases and oxidizing agents.
