Quality Control

Our D-Ribulose is produced under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, specific rotation measurement, and identity confirmation (IR), to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing all specifications are provided with each shipment and are available upon request.

Storage

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