Description and Uses

Bisphenol S, also known as 4,4'-Sulfonyldiphenol, abbreviated as BPS, is a synthetic bisphenol (BP) compound. It was originally used as a safe alternative to bisphenol A and is present in many household products, including food packaging, beverage containers, lotions, toys, plastic PVC floors and water pipes[1]. However, current studies have found that BPS does not seem to be very safe and may damage the function of melanocytes[2]. Higher BPS exposure is also associated with increased serum uric acid concentrations, and this association is more obvious in boys, which poses certain health hazards[3].

Bis(4-hydroxyphenyl) Sulfone is commonly used as a reactant in epoxy reactions and is also used as a latent thermal catalyst for epoxy resin.
