Description

Isobutanethiol CAS NO 513-44-0 is a volatile organosulfur compound characterized by its distinctive, powerful odor. This chemical serves as a critical intermediate and additive in various industrial synthesis processes, where its thiol functionality is essential. It is primarily utilized by manufacturers in the agrochemical, pharmaceutical, and specialty chemical sectors for applications ranging from synthesis to odorant formulation.

Application

• Chemical Synthesis Intermediate: A key building block for synthesizing more complex sulfur-containing compounds, including certain pesticides and pharmaceuticals.
• Agrochemical Production: Used in the manufacture of specific fungicides and insecticides where the thiol group acts as a reactive site.
• Odorant and Warning Agent: Employed in trace amounts in natural gas, propane, and other odorless fuels to provide a detectable safety warning.
• Flavor and Fragrance Ingredient: Serves as a precursor or component in creating specific savory or sulfurous notes in advanced flavor and fragrance compositions.
• Polymer and Rubber Industry: Acts as a chain transfer agent or modifier in certain polymerization processes to control molecular weight.
• Research & Development: Used in organic chemistry research as a reagent for introducing the tert-butylthio group or for studying thiol-based reactions.
