Description

Applications
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.

Solubility
Slightly soluble in water. Miscible with alcohol, ether, chloroform, etherMiscible with alcohol, ether, chloroform and ether. Slightly miscible with water.

Notes
Store in a cool place. Incompatible with bases, oxidizing agents, reducing agents and alkali metals.
