Quality Control

Our L-Quebrachitol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including HPLC for purity, chiral analysis, and identification by IR and NMR to ensure identity and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We can support development projects with material meeting various purity grades, including research and pharmaceutical intermediate standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties.
