Demethoxylate

Part of speech: verb

Definitions

1. Strips the methoxy group, an oxygen bonded to a methyl group, away from a molecule in a chemical reaction
2. Cleaves off a methoxy substituent from an organic compound, leaving behind a hydroxyl or related group
3. Removes the OCH3 side group from a chemical structure through a process of demethylation and cleavage

Etymology: "Demethoxylate" is a technical chemistry coinage built from two parts. The prefix "de-" comes from Latin, where it signified removal or reversal, as in "decapitate" or "deforest". The base "methoxylate" is itself built from "methoxy," the chemical group made of a methyl group attached to an oxygen atom, with "-ate" marking the verb form. Chemists attach "de-" to such verbs to name the reaction in which that group is stripped away from a molecule. Because "demethoxylate" is a specialist term formed by combining these familiar pieces, it has no older history of its own. Its meaning follows directly from the parts: to take a methoxy group off a compound. The word belongs to the modern vocabulary of organic chemistry, where naming a reaction precisely matters more than any literary pedigree.
