Quality Control

Our 3,3-Dimethylbutanoic Anhydride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC and identification by FTIR, to ensure it meets the high-purity standards required for synthetic applications. A Certificate of Analysis (COA) documenting purity, identity, and key physical parameters is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, strong oxidizing agents, and alcohols. Recommended storage temperature is 2-8°C for long-term stability. The product is moisture-sensitive; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent hydrolysis.
