CAS 75-28-5: Isobutane

Description: Isobutane, also known as methylpropane, is a branched-chain alkane with the chemical formula C4H10. It is a colorless, odorless gas at room temperature and pressure, and it is highly flammable. Isobutane has a boiling point of approximately -11.7 °C, making it a gas at ambient conditions but easily liquefied under pressure. It is commonly used as a refrigerant, in aerosol propellants, and as a feedstock in the petrochemical industry for the production of isooctane, which is an important component of high-octane gasoline. Isobutane is also utilized in the synthesis of various organic compounds. Its low toxicity and relatively low environmental impact compared to other hydrocarbons make it a preferred choice in many applications. However, it is important to handle isobutane with care due to its flammability and potential health hazards when inhaled in high concentrations. Overall, isobutane is a versatile chemical with significant industrial applications.
