Quality Control

Every batch of 2,5-Pyridinedicarboxylic Acid-13C8,D3 is manufactured and analyzed under strict quality systems to ensure the highest isotopic and chemical purity for research use. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing isotopic enrichment (e.g., 13C, D), chemical purity, and identity confirmation are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
