Used primarily as an intermediate in organic synthesis, this compound is valuable in the production of pharmaceuticals and agrochemicals. Its reactive sulfonyl chloride group enables it to act as a key building block for creating sulfonamide derivatives, which are widely utilized in drug development for their antibacterial and antifungal properties. Additionally, it finds application in the preparation of dyes and pigments due to its ability to introduce nitro and sulfonyl functional groups into organic molecules. Its role in chemical research is significant for designing and synthesizing novel compounds with potential biological activity.
