butyl

adj. containing the butyl group (Chemistry)

In organic chemistry, butyl is a four-carbon alkyl substituent with chemical formula -C4H9 . It is derived from either of the two isomers of the alkane called butane.Each of the two isomers of butane give rise to two isomers of the butyl substituent. Thus, n-butane can connect at either the terminal or an internal carbon atoms, giving rise to "n-butyl" and "sec-butyl" substituents.n-butyl group; CH3CH2CH2CH2–, (fully systematic name "butyl")sec-butyl group; CH3CH2(CH3)CH–, (fully systematic name "1-methylpropyl")
