Quality Control

Our 2-o-(B-D-Galactopyranosyl)-D-Galactopyranose is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, specific optical rotation, and identity confirmation by IR and NMR, to ensure it meets the exacting standards required for research and development. Certificates of Analysis (COA) detailing all test results are available upon request.

Storage

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