Quality Control

Our 4,4'-[(Dioctylstannylene)Bis(Oxy)]Bis(4-Oxo-2-Butenoic Acid) is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration or HPLC, identification by FT-IR and NMR spectroscopy, and determination of tin content and moisture levels. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
