Description

Isopropyl Methyl Disulphide is a specialized organosulfur compound with the CAS registry number 40136-65-0. This chemical serves as a versatile intermediate and a potent source of sulfur in various synthesis and industrial processes. It is particularly valuable for manufacturers in the agrochemical, fragrance, and pharmaceutical sectors seeking to introduce specific sulfur-containing functional groups into their products.

Application

• Agrochemical Intermediate: A key building block in the synthesis of novel pesticides, herbicides, and fungicides, where the disulfide linkage contributes to biological activity.
• Flavor and Fragrance Ingredient: Used to impart savory, alliaceous, or meaty notes in flavor compositions and as a component in specialty fragrance formulations.
• Pharmaceutical Synthesis: Acts as a crucial intermediate in the production of certain active pharmaceutical ingredients (APIs) that require a disulfide bridge or specific sulfur motifs.
• Chemical Research & Development: Employed in organic synthesis as a reagent for introducing the isopropylmethyl disulfide moiety or for studying sulfur-transfer reactions.
• Polymer Modification: Utilized as a cross-linking agent or modifier in the production of specialty polymers and rubbers to alter physical properties.
• Lubricant Additive Precursor: Serves as a starting material for synthesizing extreme pressure (EP) and anti-wear additives for industrial lubricants.
