Quality Control

Our Vinylnorbornene is produced and handled under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to verify identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided to ensure full traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
