Quality Control

Our 1,1'-(1,3-Propanediyl)Dithymine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We can support development projects with custom purity grades and specifications 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. For long-term storage, consider using desiccants.
