應用
trans-1,4-Dichloro-2-butene may be used for the alkylation of adenine to 9-alkylpurines. It can react with diethyl malonate to form vinylcyclopropane derivative. It can also undergo asymmetric allylic alkylation with Grignard reagents in the presence of copper thiophene carboxylate catalyst.

Several important chemicals, including formaldehyde, 1,4-dichloro-2-butene, bis-chloromethyl ether, hexamethylphosphoramide, and epichlorohydrin have been shown to produce nasal tumours in rats following repeated or continuous inhalation exposures. Some of these compounds are respiratory irritants. To determine whether there is a correlation
