Basic Information of Cyclobutane
Cyclobutane (CAS No. 287-23-0) is a colorless, highly flammable gas at room temperature and pressure, which readily condenses to a liquid below its boiling point of approximately 12.5°C. Its four-membered ring structure gives it distinctive chemical properties, leading to its niche but essential roles in cutting-edge synthesis and analysis.
