Cyclobutane is a cycloalkane organic compound with the formula (CH2)4, a colorless gas at room temperature. Cyclobutane is usually sold as a liquified gas (a gas that has been pressurized or frozen to be in a state that isn't natural). Variants of cyclobutane are called cyclobutanes. Cyclobutane has no uses in commerce or biology,[1] but compounds containing cyclobutane are important in biology and biotechnology.
Structure
The carbon atoms within cyclobutane are at odd angles. Cyclobutane is unstable and will break at temperatures over about 500° celcius. Cyclobutane is connected to itself in a ladder-like structure. An example of this structure can be seen in the pentacycloanammoxic acid. This compound is a ladderane made up of five connected cyclobutane units.
