Quality Control

Every batch of Endo-3 7 14-Tris(Dimethylsilyloxy)-Hept& CAS NO 307496-30-6 is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the exacting standards required for pharmaceutical and advanced synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation, as the compound is sensitive to strong bases and should be kept away from such materials.
