Butyl

Butyl (pronounced /ˈbjuːtaɪl/) is a functional group in organic chemistry with the formula -C4H9. The term is derived from the Greek word "butyros", meaning butter, as butyric acid was first detected in butter.

Etymology

The term "butyl" is derived from "butyric acid", a compound originally discovered in rancid butter. The name "butyric acid" comes from the Greek word "βούτῡρον" (būtūron), meaning "butter", combined with the chemical suffix "-yl", which is from the Greek "hūlē", meaning "matter" or "stuff".
