CAS No. 75-94-5 is an organic compound known as 2-methyl-propane, or isobutane. It is a colourless, flammable gas with a petroleum-like odour. Isobutane is a member of the alkane family of hydrocarbons and is used as a refrigerant and as a propellant in aerosol cans.
Isobutane is a four-carbon alkane with the chemical formula C4H10. It is an isomer of the normal butane, and can be produced by distilling butane. Isobutane is a non-polar molecule, meaning it does not easily dissolve in water. It has a boiling point of -12.7 degrees Celsius, a melting point of -138.4 degrees Celsius, and a density of 2.48 grams per litre.
Isobutane is used as a refrigerant in household and commercial refrigerators, freezers, and air conditioners. It is also used as a propellant in aerosol cans, such as hairspray, deodorant, and insect repellent. Its low boiling point and low volatility make it an excellent propellant for aerosols.
Isobutane is also used as a fuel in portable camping stoves and lanterns, and can be used as a fuel for cars and motorcycles. It is also used as a fuel in fuel cells, which are an alternative energy source.
Isobutane is a relatively safe and non-toxic gas. However, its flammability means that it must be handled with care. It is also important to ensure that all containers are properly sealed to prevent any leaks.
Overall, CAS No. 75-94-5 is an organic compound known as 2-methyl-propane, or isobutane. It is a colourless, flammable gas with a petroleum-like odour. Isobutane is used as a refrigerant and as a propellant in aerosol cans, and can also be used as a fuel for cars and motorcycles. It is relatively safe and non-toxic, but must be handled with care due to its flammability.
