4-Hydroxybenzenesulfonic acid

Description:

4-Hydroxybenzenesulfonic acid, also known as para-hydroxybenzenesulfonic acid, is an aromatic sulfonic acid characterized by the presence of both a hydroxyl (-OH) group and a sulfonic acid (-SO3H) group attached to a benzene ring. Its molecular formula is C6H7O3S, and it features a sulfonic acid functional group that imparts strong acidity, making it soluble in water. This compound is typically a white to light yellow crystalline solid and is known for its role as a reagent in organic synthesis and as an intermediate in the production of dyes, pharmaceuticals, and other chemical compounds. The presence of the hydroxyl group allows for hydrogen bonding, enhancing its solubility in polar solvents. Additionally, 4-hydroxybenzenesulfonic acid exhibits antioxidant properties and can participate in various chemical reactions, including sulfonation and esterification. Its CAS number, 98-67-9, is used for identification in chemical databases and regulatory contexts. Safety precautions should be observed when handling this compound, as it can be corrosive and irritative.

4-Hydroxybenzenesulfonic acid, 65% aqueous solution

CAS: 98-67-9

4-Hydroxybenzenesulfonic acid is a chemical compound that is used as an antimicrobial agent in industrial applications. It is commonly used as a corrosion inhibitor, a chelating agent, and an additive for detergents and other cleaning products. 4-Hydroxybenzenesulfonic acid has been shown to inhibit the growth of bacteria by binding to fatty acids in the cell membrane and preventing them from being incorporated into the cell wall. This process causes the cell wall to weaken and eventually rupture. The reaction mechanism of 4-hydroxybenzenesulfonic acid is similar to that of p-hydroxybenzoic acid, which also inhibits bacterial growth by attacking fatty acids in the cell membrane. 4-Hydroxybenzenesulfonic acid may be preferable because it can be produced from renewable sources rather than from petroleum or natural gas.
