*Bisphenol A* (*BPA*) is a carbon-based synthetic compound with the
chemical formula (CH[3])[2]C(C[6]H[4]OH)[2] belonging to the group of
diphenylmethane derivatives and bisphenols. It has been in commercial use
since 1957.

BPA is part of the bisphenols group of chemical compounds with two
hydroxyphenyl groups. It is a colorless solid that is soluble in organic
solvents, but poorly soluble in water. Bisphenol A has a vapor pressure of
5×10^−6 Pa.^[1]

BPA is employed to make certain plastics and epoxy resins. BPA-based
plastic is clear and tough, and is made into a variety of common consumer
goods, such water bottles, sports equipment, CDs, and DVDs. Epoxy resins
containing BPA are used
