Quality Control

Our S-Propyl-5-Nitro-2-Thiobarbituric-D7 Acid is manufactured under strict quality systems to ensure the highest isotopic purity and chemical integrity. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing results for isotopic enrichment (D-content), chemical purity, and identity confirmation. We adhere to relevant standards for stable isotope-labeled compounds to support your regulatory and research requirements.

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 nature, the container must be kept sealed in a dry environment to prevent moisture absorption, which can affect stability and purity. For long-term storage, consider desiccants or inert atmosphere.
