Bisphenol

The bisphenols (/ˈbɪsfɪnɒl/) are a group of industrial chemical compounds related to diphenylmethane; commonly used in the creation of plastics and epoxy resins.^[1][2][3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter following denotes the variant, which depends on the additional substituents. Bisphenol A is the most popular representative of the group, with millions of metric tons produced globally in the past decade, often simply called "bisphenol".^[3][4][5]
