Alkylation with geminal dihalides gives 1,3-dithiepanes.  Oxidation gives the cyclic disulfide 1,2-dithiane:
It forms self-assembled monolayers on gold.
It is also used in polyadditions along with 1,4-butanediol to form sulfur-containing polyester and polyurethanes containing diisocyanate. Several of these polymers are considered biodegradable and many of their components are sourced from non-petroleum oils.
