"Bisphenol" is a common name, the following letter refers to one of the reactants. Bisphenol A is the most popular representative of this group, often simply called "bisphenol."
|Structural formula||Name||CAS||Reactants||Systematic name|
|Bisphenol S||80-09-1||Phenol||Sulfur trioxide||Bis(4-hydroxyphenyl)sulfone|
|Bisphenol PH||24038-68-4||2-Phenylphenol||Acetone||5,5’ -(1-Methylethyliden)-bis[1,1’-(bisphenyl)-2-ol]propane|
Bisphenols A and S are endocrine disruptors. These products tend to release from the material when heated; as a precaution, it is recommended for the consumer:
- not to heat food in a plastic packaging in a microwave oven, or a tin can (its inside coating is often epoxy) with a bain-marie;
- use a pitcher material other than plastic, not a plastic bottle.
