The molecule is a methanesulfonate ester that is butane-1,4-diol in which the hydrogens of the hydroxy groups are replaced by methanesulfonyl groups. An alkylating antineoplastic agent, it is used for the treatment of chronic myeloid leukemia (although it has been largely replaced by newer drugs). It is also used as an insect sterilant. It has a role as an insect sterilant, an antineoplastic agent, a teratogenic agent, a carcinogenic agent and an alkylating agent. It derives from a butane-1,4-diol.
