Description

1,2-Butanedithiol CAS NO 16128-68-0 is a versatile organic sulfur compound featuring two thiol groups on adjacent carbon atoms, making it a valuable building block and reagent in synthetic chemistry. Its primary commercial value lies in its ability to act as a potent nucleophile and a source of sulfur, facilitating the synthesis of complex molecules and materials. This chemical is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require precise and reliable sulfur-containing intermediates.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing thioether or disulfide linkages.
• Agrochemical Synthesis: Serves as a key precursor in the production of certain fungicides and pesticides where sulfur incorporation is critical for bioactivity.
• Polymer Modification: Acts as a chain transfer agent or cross-linking agent in the production of specialty polymers and rubbers to modify physical properties.
• Chemical Research & Development: Employed as a versatile reagent for organic synthesis, including nucleophilic addition reactions and the preparation of heterocyclic compounds.
• Flavor & Fragrance Industry: Utilized in the synthesis of certain sulfur-containing aroma chemicals, contributing to savory or roasted notes.
• Material Science: Used in surface functionalization and the creation of self-assembled monolayers (SAMs) on metal surfaces.
