Quality Control

Our Tpd-Osu is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, suitable for sensitive synthetic applications. Each lot is analyzed using advanced chromatographic and spectroscopic techniques, including HPLC and NMR, to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment 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 (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
