Product Description


1,3-Dimercaptopropane CAS #109-80-8

1, 3-dimercaptopropane is usually a colorless transparent liquid at room temperature. However, due to its easy oxidation and other reasons, it may be slightly yellow after long-term storage.

It is a liquid state at room temperature and atmospheric pressure, with a certain fluidity, its density is slightly larger than water, slightly soluble in water, can be mixed in ethanol, ether, benzene, chloroform and other organic solvents.

Product Usage

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.
