Dimethyl fumarate is an electrophile that chemists often use in Diels–Alder reactions. In the 1950s, German and Swiss physicians found that dimethyl fumarate is an effective topical treatment for psoriasis. More recently, building on the link between psoriasis and multiple sclerosis (MS), researchers have assessed dimethyl fumarate as a possible MS treatment.
