The antitumor agent N,N'-bis(2-chloroethyl)-N-nitrosourea (BCNU) is known to be unstable in aqueous solution, and to degrade spontaneously to reactive alkylating and carbamoylating intermediates. Whereas the alkylating component is believed to be responsible for the antitumor effects of this drug, it
