Description

1,4-Butanedithiol CAS NO 1191-08-8 is a versatile organic sulfur compound characterized by two thiol (-SH) groups at the terminal positions of a four-carbon chain. This bifunctional structure makes it a valuable building block in organic synthesis, particularly for creating sulfur-containing heterocycles and as a linker in polymer chemistry. It is primarily sought by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring precise molecular assembly and functional group introduction.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing sulfur-containing active pharmaceutical ingredients (APIs) and heterocyclic compounds.
• Polymer Chemistry: Acts as a cross-linking agent or chain extender in the production of specialty polymers, polyurethanes, and epoxy resins.
• Agrochemical Synthesis: Used in the manufacture of certain pesticides and fungicides where the dithiol moiety is integral to biological activity.
• Ligand Synthesis: Serves as a precursor for chelating agents and ligands used in catalysis and metal complexation.
• Material Science: Employed in surface modification and the creation of self-assembled monolayers (SAMs) on gold and other surfaces.
• Organic Synthesis: A versatile reagent for thioacetalization reactions and as a source of sulfhydryl groups in multi-step synthetic routes.
