Isopentane Specification

The Isopentane, with the CAS registry number 78-78-4,is also known as 2-Methylbutane. It belongs to the product categories of Industrial/Fine Chemicals;refrigerants;Organics. Its EINECS number is 201-142-8. This chemical's molecular formula is C5H12 and molecular weight is 72.15. What's more,Its systematic name is Isopentane. It is a colourless liquid with a characteristic smell. And it can be used as a solvent of polyethylene, also can be made of polystyrene foam, polyurethane foam system, foam, solvent de-asphalting. It is a low toxic, flammable liquids, burning will produce irritation of smoke, need to store in the cold and dry environment, and stored separately with oxidants and acids. dry powder, dry sand, carbon dioxide, foam can be used if something urgent happened.
