[1,1′-Biphenyl]-4-sulfonic acid

Description:
[1,1′-Biphenyl]-4-sulfonic acid, with the CAS number 2113-68-0, is an organic compound characterized by the presence of a biphenyl structure substituted with a sulfonic acid group at the para position. This compound typically appears as a white to light yellow solid and is soluble in water due to the polar sulfonic acid functional group. It exhibits acidic properties, making it useful in various chemical reactions and applications, including as a reagent in organic synthesis and as a pH indicator. The sulfonic acid group enhances its reactivity, allowing it to participate in electrophilic aromatic substitution reactions. Additionally, [1,1′-Biphenyl]-4-sulfonic acid can serve as a surfactant or dispersing agent in different industrial processes. Its stability under normal conditions and its ability to form salts with bases further contribute to its utility in chemical applications. Safety precautions should be observed when handling this compound, as with many sulfonic acids, due to potential irritant properties.
