Quality Control

Our 1,2-Diethylidenecyclobutane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
