Quality Control

Our Xylopyranose, 2,3-Di-o-Methyl-, .Beta.-D- is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation needs.

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.
