Quality Control

Our D-Arabinose (2-13C) is manufactured under strict quality control protocols to ensure exceptional isotopic and chemical purity for research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (Atom % 13C), chemical purity, and specific optical rotation. We adhere to cGMP principles for the production of fine chemicals to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a 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 purity.
