Sulfuric acid mono-m-tolyl ester, also known as methyl 3-methylbenzenesulfonate, is an organic compound with the chemical formula C8H10O3S. It is a colorless to pale yellow liquid that is soluble in organic solvents and has a pungent odor. This ester is derived from the reaction of sulfuric acid with m-toluic acid, where one hydroxyl group of the m-toluic acid is replaced by a sulfonyl group. It is used as an intermediate in the synthesis of various chemicals, including pharmaceuticals and dyes, and as a reagent in organic chemistry. Due to its reactivity, it is important to handle sulfuric acid mono-m-tolyl ester with care, as it can be corrosive and harmful if not properly managed.
