General description

Ammonium sulfide is an organosulfur compound, mainly used as a flavor ingredient due to its characteristic sulfurous odor. The fried bacon aroma produced during the reaction of ammonium sulfide with isovaleraldehyde is due to 2,4,6-triisobutyl-4H-1,3,5-dithiazine and 3,5-diisobutyl-1,2,4-trithiolane formed during the reaction.
