Used primarily in the production of viscose rayon and cellophane film, where it reacts with cellulose to form a soluble compound that can be spun into fibers. Also serves as a solvent in industrial applications, especially in the manufacture of rubber chemicals and pesticides. Plays a role in the synthesis of certain organosulfur compounds used in rubber vulcanization accelerators. Historically used as a fumigant for soil and stored grains, though this use has declined due to toxicity and environmental concerns. Occasionally employed in mining operations as a flotation agent for certain ores.
