Quality Control

Our Norbornene Anhydride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure it meets high-purity standards suitable for demanding applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every 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 at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
