o-Toluenesulfonic acid

Description:
o-Toluenesulfonic acid, also known as 2-toluenesulfonic acid, is an aromatic sulfonic acid characterized by its strong acidity and solubility in water and organic solvents. It appears as a colorless to pale yellow crystalline solid or a viscous liquid, depending on its form. The compound has a molecular formula of C7H8O3S and a molecular weight of approximately 174.2 g/mol. It is commonly used as a catalyst in organic synthesis, particularly in the production of esters and ethers, due to its ability to protonate substrates and enhance reactivity. Additionally, o-toluenesulfonic acid serves as a reagent in various chemical reactions, including the synthesis of pharmaceuticals and polymers. Its hygroscopic nature allows it to absorb moisture from the air, which can affect its handling and storage. Safety precautions are necessary when working with this compound, as it can cause irritation to the skin, eyes, and respiratory system. Proper protective equipment should be used to mitigate exposure risks.
