CAS 609-54-1

2,5-Dimethylbenzenesulfonic acid

Description:

2,5-Dimethylbenzenesulfonic acid, with the CAS number 609-54-1, is an aromatic sulfonic acid characterized by the presence of a sulfonic acid group (-SO3H) attached to a dimethyl-substituted benzene ring. This compound typically appears as a white to light yellow solid and is soluble in water due to the polar sulfonic acid group, which enhances its reactivity and ability to participate in various chemical reactions. It is commonly used as a reagent in organic synthesis, particularly in the preparation of sulfonamides and other sulfonated compounds. The presence of methyl groups on the benzene ring influences its acidity and steric properties, making it a useful intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals. Additionally, 2,5-dimethylbenzenesulfonic acid can act as a catalyst in certain reactions, showcasing its versatility in chemical processes. Safety precautions should be observed when handling this compound, as it can be irritating to the skin and eyes.
