Quality Control

Our Dimethyl[Spiro[Dibenz[B,E]Oxepin-11(6H),2'-[1,3]Dioxolane]-4'-Methyl]Ammonium Maleate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for pharmaceutical intermediate applications. A comprehensive Certificate of Analysis (COA) detailing all test results and specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
