Used primarily as a chemical intermediate in the synthesis of various organic compounds. It plays a key role in the production of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs). Additionally, it is utilized in the manufacturing of agrochemicals, including herbicides and pesticides, where it acts as a building block for more complex molecules. Its reactivity with other compounds makes it valuable in organic synthesis, enabling the creation of sulfonyl-containing derivatives. In industrial applications, it is sometimes employed in the production of specialty chemicals, such as surfactants or polymers, where its sulfonyl group contributes to desired properties like solubility or stability.
