Quality Control

Our trans-5-Norbornene-2,3-Dicarbonyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to cGMP guidelines where applicable, and each lot is accompanied by a comprehensive Certificate of Analysis (COA). The COA includes data for purity (by HPLC or GC), identity confirmation (by IR and NMR), and critical impurity profiles. We are committed to meeting the stringent specifications required for pharmaceutical and advanced material applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and amines. Containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as strong bases and oxidizing agents.
