Quality Control

Our (2R)-2-Bromo-1,4-Butanediol is manufactured under strict quality control protocols to ensure high chemical and chiral purity. Each batch is analyzed using advanced techniques including HPLC, GC, and chiral analysis to confirm identity, potency, and enantiomeric excess. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific project requirements.

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 nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong bases and oxidizing agents.
