General description

Butyl sulfide is a volatile sulfur compound that can be used as a flavoring agent.

Application


  • Room-Temperature Synthesis of Thioether-Stabilized Ruthenium Nanocubes and Their Optical Properties.: This article presents a method for synthesizing thioether-stabilized ruthenium nanocubes at room temperature, using butyl sulfide as a stabilizing agent. The study details the optical properties of the nanocubes, which could have implications for their use in catalysis and materials science (Adams et al., 2023).
