Quality Control

Our D-Glycero-D-Talo-Heptitol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification by spectroscopic methods (NMR, IR) and purity assessment by chromatography (HPLC), to ensure it meets high-purity research-grade standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency for your critical research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect stability and purity. For long-term storage, consider using a desiccant in the storage environment.
