Quality Control

Our Carboxyphosphamide Benzyl Ester-D4 is manufactured under strict quality systems to ensure the high isotopic purity and chemical integrity required for analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D-content), chemical purity by HPLC, and identity confirmation. We adhere to relevant industry standards to support GLP and GMP research.

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 sensitivity to strong acids and organic solvents, keep away from incompatible materials. For long-term storage, consider storing under an inert atmosphere to ensure maximum stability.
