Used as a powerful sulfonating and silylating reagent in organic synthesis. It efficiently introduces sulfonyl groups into aromatic and heteroaromatic compounds under mild conditions. Commonly applied in the preparation of sulfonate esters, which serve as intermediates in pharmaceuticals and agrochemicals. Also useful for the protection of hydroxyl groups via silylation, enabling selective transformations in complex molecule synthesis. Its high reactivity allows for fast reactions at low temperatures, improving yield and reducing side products. Handles moisture-sensitive reactions effectively when used in anhydrous environments.
