This chemical is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. Its chlorosulfonyl group makes it a valuable building block for creating sulfonamide derivatives, which are commonly found in drugs with antibacterial, anti-inflammatory, or diuretic properties. Additionally, it can be utilized in the development of herbicides or pesticides due to its reactive functional groups, which allow for further chemical modifications. Its ester group also provides versatility in organic synthesis, enabling the creation of compounds with specific biological activities.
