Quality Control

Our 2-Oxa-8-Azaspiro[4.5]Decane Hemioxalate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (NMR, IR, MS), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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. Keep away from incompatible materials.
