Bisphenols

Part of speech: noun

Definitions

1. A group of chemical entities produced from phenol and two distinct alkyl groups A subset of organic compounds mainly employed in the production of plastics and synthetic resins Various forms derived from phenol that can disrupt normal endocrine system activities in organisms
2. Organic chemicals composed of two phenol groups linked by a bridging structure, commonly used in manufacturing plastics
3. Molecules consisting of two phenol rings connected by a central atom or group, often involved in the production of polymer materials

Etymology: "Bisphenols" is the plural of "bisphenol", and its story is mostly one of compounding. The first part, "bis-", is a Latin prefix meaning "twice" or "double", and it attaches to "phenol", a word for a family of carbolic-type compounds. Phenol itself has an unexpected ancestry: it was coined from French "phène", which came from the Greek verb "phainō", meaning "to shine" or "to appear", a reference to the illuminating gas that early chemists first obtained from coal tar, where the compound was found. A chemist's word for a shining gas, then, sits at the root of a term for molecules built from two such units. The Greek connection is the surprising part. "Phainō" also gave English words such as "phenomenon", so phenol and phenomenon share a remote ancestor in the idea of appearing or showing. The "bis-" prefix, by contrast, is a plain Latin piece that chemists used to mark a doubled structure, the same way they used it in terms like "bisulfate".
