Quality Control

Our L-(+)-Threose is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including chiral purity verification and impurity profiling. A detailed Certificate of Analysis (COA) documenting identity, purity, and specific tests is provided with every shipment to support your research and quality assurance requirements.

Storage

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