2-Sulfobenzoic acid cyclic anhydride

Description:
2-Sulfobenzoic acid cyclic anhydride, also known as 2-sulfobenzoic anhydride, is an organic compound characterized by its cyclic anhydride structure derived from 2-sulfobenzoic acid. This compound typically appears as a white to off-white solid and is soluble in polar organic solvents. It features a sulfonic acid group, which contributes to its reactivity and makes it useful in various chemical applications, including as a reagent in organic synthesis. The cyclic anhydride form allows for the formation of acylating agents, which can facilitate the introduction of acyl groups into other molecules. Its reactivity is influenced by the presence of the sulfonic group, making it a valuable intermediate in the synthesis of pharmaceuticals and agrochemicals. Additionally, it is important to handle this compound with care due to potential irritant properties. Overall, 2-sulfobenzoic acid cyclic anhydride serves as a significant building block in organic chemistry, particularly in the development of more complex chemical entities.
