Quality Control

Our 5-Norbornene-2-Carboxaldehyde is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) due to its easily oxidized nature. Keep away from heat, sparks, and open flames. Due to high volatility, ensure containers are securely sealed when not in use.
