2-ethylhexyl is an eight-carbon branched alkyl substituent used in organic chemistry. It is derived from 2-ethylhexane and is commonly represented as the substituent name octan-2-yl; in many commercial contexts the name 2-ethylhexyl is preferred. The group is also known by synonyms such as iso-octyl or isooctyl, reflecting its relationship to the isooctyl family of branched octyl groups.
