1 4-Dichlorobutane is primarily used as an intermediate in the synthesis of other organic chemicals including pharmaceuticals specialty chemicals and polymers.

Its main purpose is to serve as a chemical building block and bifunctional alkylating agent allowing chemists to introduce a four-carbon chain containing reactive chloride groups into other molecules.

1 4-Dichlorobutane is a colorless to pale liquid . It contains two reactive chlorine atoms at opposite ends of the butane chain which makes it useful for chemical synthesis.
