Benzenesulfonic acid, 4-methoxy-

Description:

4-Methoxybenzenesulfonic acid, also known as p-methoxybenzenesulfonic acid, is an aromatic sulfonic acid characterized by the presence of a methoxy group (-OCH₃) attached to the benzene ring at the para position relative to the sulfonic acid group (-SO₃H). This compound is typically a white to light yellow solid that is soluble in water and organic solvents, reflecting its polar sulfonic acid functional group. It exhibits acidic properties due to the sulfonic acid moiety, making it a strong acid compared to carboxylic acids. The presence of the methoxy group can influence its reactivity and solubility, often enhancing its nucleophilicity and making it useful in various chemical reactions, including sulfonation and as a reagent in organic synthesis. Additionally, 4-methoxybenzenesulfonic acid can serve as a surfactant or an intermediate in the production of dyes, pharmaceuticals, and other chemical products. Safety precautions should be taken when handling this compound, as it may cause irritation to the skin and eyes.
