Quality Control

Every batch of 2-(Acetoxymethoxy)-1,3-Propanediyl-D5 Dibenzoate is produced and tested under strict quality management protocols to ensure the high isotopic purity and chemical integrity required for analytical applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing isotopic enrichment (D5), 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 dry environment to prevent degradation. For long-term storage, consider using desiccants.
