Quality Control

Every batch of 263E CAS NO 63278-67-1 is manufactured under a strict quality management system. Our products undergo rigorous analytical testing to ensure they meet the high-purity standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
