Description

General description

Butyl sulfide is a volatile organic sulfur compound that is used as an organic building block in chemical synthesis. It is used to prepare dibutyl sulfoxide (DBSO) via oxidation reaction. DBSO is used as a valuable organic solvent for the extraction of zirconium, palladium, platinum, and gold.

Application

• Environmental Odor Diagnostics: Dibutyl sulfide was utilized in developing a diagnostic method for complex odor issues in micro-polluted source water, highlighting its role in environmental monitoring and pollution control (Guo et al., 2021).
• Surface Chemistry Investigations: The adsorption and manipulation of dibutyl sulfide on copper surfaces were studied, providing insights into its interactions at the molecular level (Jensen et al., 2007).
• Biosensor Development for Chemical Warfare Detection: Dibutyl sulfide′s effects were explored in the context of stand-off tissue-based biosensors for detecting chemical warfare agents, utilizing photosynthetic fluorescence induction, it is crucial in constructing the inertial forces of launching or dropping into suspected danger zones and, with encrypted telecommunication data transmission (Sanders et al., 2001).
