Also known as 1,​2-​Dithiolane, 1,2-Dithiacyclopentane, Trimethylene disulfide

1,2-Dithiolane is an organosulfur compound with the formula . It is also classified as a heterocycle derived from cyclopentane by replacing two methylene bridges ( units) with a disulfide group. 1,3-Dithiolane is an isomer. The parent molecule is unimportant but substituted derivatives, especially lipoic acid and its derivatives, are often essential for life. Several occur naturally.
