Quality Control

Every batch of D-Arabinose-1-13C is manufactured and analyzed under strict quality management systems. We provide comprehensive Certificates of Analysis (COA) detailing isotopic purity (atom % 13C), chemical purity (by HPLC), and specific analytical data including optical rotation and residual solvent content. Our quality commitment ensures the material meets the stringent requirements for research and diagnostic applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect stability and analytical performance.
