Quality Control

Our Hexafluorocyclobutene is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flames. For long-term storage, keep under an inert atmosphere (e.g., nitrogen or argon) in a temperature-controlled environment (recommended 2-8°C or as specified).
