Product Technical Details

Product Overview

1,4-Butanedithiol (CAS 1191-08-8) is a bifunctional aliphatic dithiol compound widely employed as a versatile intermediate in advanced organic synthesis. With two reactive thiol (-SH) groups positioned at terminal carbon atoms, it serves as a critical crosslinking agent, chelating ligand, and precursor in the production of polymers, pharmaceutical intermediates, and functional materials. Its high reactivity and molecular symmetry make it particularly valuable in the development of sulfur-containing architectures.

Industrial Applications

As a specialty intermediate, 1,4-Butanedithiol is primarily utilized in research and industrial-scale chemical processes requiring precise sulfur incorporation. Key application areas include:

  • Synthesis of thiol-ene photopolymerizable resins and coatings
  • Preparation of metal-chelating agents and stabilizers
  • Building block for heterocyclic compounds in agrochemical and fine chemical R&D
  • Crosslinking component in elastomer and adhesive formulations

Due to its sensitivity to oxidation, proper handling under inert atmosphere and storage in cool, well-ventilated conditions are essential to maintain product integrity.
