1,3-Dimercaptopropane CAS #109-80-8
1,3-Dimercaptopropane is a colorless to pale yellow transparent liquid. It has a strong and unpleasant odor (similar to the characteristic irritating smell of mercaptans). It is slightly soluble in water, but readily soluble in most organic solvents such as ethanol and ether. This substance is flammable and has strong irritancy and corrosiveness to the skin, eyes and respiratory tract.

1,3-Dimercaptopropane CAS #109-80-8 Application
The main application fields of 1,3-Dimercaptopropane:
Chemical synthesis intermediate: In organic synthesis, it is often used as a bifunctional linker or protecting group reagent. For example, it reacts with aldehydes or ketones to form 1,3-dithiopentane, thereby protecting the carbonyl group.
Pharmaceuticals and pesticides: As a fine chemical intermediate, it is used for the synthesis of certain specific drug molecules, antibacterial agents or pesticides.
High polymer materials: It can be used for the synthesis of special sulfur-containing polymers or as a crosslinking agent for resins.
Metal complexing agent: Due to the strong affinity of the mercapto group for heavy metal ions, it can be used for the complexation, extraction of metal ions or as a detoxifying agent for heavy metal poisoning research.
