Root Explanation

Catechol is formed from "catech" (from the Greek "kathechein", meaning to hold down or to restrain) and "-ol" (a suffix used in chemistry to denote alcohols or phenolic compounds). The word refers to a specific type of chemical compound that is a dihydroxybenzene, holding down two hydroxyl groups on a benzene ring.

Memory Tip

Think of 'holding down' ('catech') two 'hydroxyl groups' ('-ol') on a benzene ring — that's what catechol represents in chemistry.
