Dimethyl Sulfoxide → HCID 86733200, compound

Participants

Reaction Steps

One and one-tenth grams of L-cysteic acid monohydrate was treated with 4 ml of DMSO. It slowly dissolved with swirling and some heating. Five ml of acetone was then added with swirling. Toward the end of this addition, a crystallization set in. After a period, 2 ml more of acetone were added. Then, after cooling with ice, the crystalline product was filtered off. Obtained 1.37 g of L-cysteic acid-DMSO molecular compound (yield, 94%). This sintered at 160°C. then gradually decomposed on heating to 180°C.
