PHENOLSULFONIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Phenolsulfonic acid is an aromatic sulfonic acid with the chemical formula C6H6O4S. It is a white crystalline solid or liquid used as a catalyst in organic synthesis, particularly in esterification and polymerization reactions. Phenolsulfonic acid is also employed in the production of resins, dyes, and pharmaceuticals. Handling requires caution due to its corrosive nature and potential health hazards, including skin and respiratory irritation. Proper storage in a cool, well-ventilated area and adherence to safety protocols are essential to ensure safe usage and prevent environmental contamination.
