Part of speech: noun

Definitions

1. A salt or ester derived from octanoic acid, commonly involved in chemical reactions or as a lubricant additive
2. A chemical compound formed by combining octanoic acid with a metal or organic group, often used in industrial or biochemical contexts
3. A substance consisting of the octanoic acid moiety bonded to another atom or group, used in various manufacturing processes and organic synthesis

Etymology: "Octanoate" is a plain chemical coinage, built by adding the standard chemistry suffix "-ate" to "octanoic acid". The "-ate" ending marks a salt or ester of an acid, so an octanoate is whatever results when the acid's hydrogen is replaced by a metal or when it combines with an alcohol. The first part of the name is also systematic. "Octa-" is Greek for eight, and the carbon chain of octanoic acid has eight carbon atoms, including the carboxyl carbon. Chemists named the acid this way so that the name itself reveals the chain length, and the salts and esters then inherit that root by the same pattern used for acetate, butyrate and other members of the series.
