Quality Control

Every batch of Diflubenzuron‐D4 is produced and analyzed under strict quality management protocols to ensure exceptional isotopic purity and chemical identity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing isotopic enrichment, chemical purity, and analytical method results (e.g., NMR, HPLC, MS) are available upon request.

Storage

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