in chemistry, a group of atoms (C₄H₉) derived from butane that bonds to other elements to form various chemical compounds.
From butane (itself from butane = bu- from butyric acid + -ane hydrocarbon suffix) plus -yl (a chemical suffix indicating a group of atoms), created in early 19th-century organic chemistry.
Butyl is invisible chemistry you touch constantly—it's in rubber, sealants, and manufacturing processes. The -yl suffix codes the whole periodic table's practical uses.
