Beschreibung

1,3-Propanedithiol is used as a reagent in the preparation of thioketals and thioacetals. It acts as a flavoring agent. It is used as a precursor in the synthesis of cyclic dithioacetal (1,3-dithiane) derivatives of carbonyl compounds. It is involved in the preparation of diiron propanedithiolate hexacarbonyl by reacting reaction with triiron dodecacarbonyl. Further, it is used for the protection of aldehydes and ketones through their reversible formation of dithianes. In addition to this, it reacts with metal ions to form chelate rings.
