Bisphenol A (BPA) is an organic 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, with two hydroxyphenyl groups.It is a colorless solid that is soluble in organic solvents, but poorly soluble in water.isphenol A is used primarily to make plastics, and products using bisphenol A-based plastics have been in commercial use since 1957. At least 3.6 million tonnes (8 billion pounds) of BPA are used by manufacturers yearly.
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of a hydroxyl group (â O H) bonded directly to an aromatic hydrocarbon group.The simplest of the class is phenol, which is also called carbolic acid C 6H 5OH.oss of a positive hydrogen ion (H +) from the hydroxyl group of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides, although the term aryloxides is preferred according to the IUPAC Gold Book.
