Descripción general
Benzenesulfonic acid, also known as besylic acid, is a strong organic acid commonly used as an acid catalyst in various organic reactions, such as esterification, alkylation, and condensation reactions. It is also used as a sulfonating agent to introduce sulfonic acid (SO3H) groups into organic compounds, which can be useful in the synthesis of several dye intermediates.
