Used as a model compound in hydrodesulfurization (HDS) studies due to its high resistance to sulfur removal. Its presence in crude oil represents a challenge in deep desulfurization processes, making it important for evaluating catalyst efficiency in refineries. Also employed in research for developing advanced desulfurization technologies, including oxidative desulfurization and biodesulfurization methods. Its stable aromatic structure makes it useful in studies of environmental persistence and fate of sulfur-containing pollutants.
