  • Applications

    Propyl sulfide (CAS 111-47-7) is a simple thioether primarily used as an intermediate in the synthesis of sulfur-containing compounds; it serves as a solvent for organic reactions and processing steps in chemical manufacturing; it may act as a fragrance component or odorant in perfumery formulations at low levels; it is also used as a processing aid in coatings, inks, and adhesives formulations; and it serves as a precursor for sulfur-containing polymers and plastic additives used in plastics.
