Monosulfate

Part of speech: noun

Definitions

1. A chemical salt or ester that contains a single sulfate group within its molecular structure, often used in chemistry and industrial processes
2. A compound formed from one sulfate unit, typically encountered as a salt or ester in laboratory and industrial chemistry
3. Any salt or ester whose molecule carries just one sulfate group, a term used in chemical classification and analysis

Etymology: Monosulfate is a plain technical coinage, built from the Greek prefix "mono-", meaning "one" or "single", attached to "sulfate". The word therefore names a chemical salt or ester containing a single sulfate group, as opposed to compounds carrying two or more. The "sulfate" half has a longer history. It comes from the chemistry of the early modern and modern periods, where "sulfuric acid" gave rise to a family of salts and esters named by adding the suffix "-ate" to the acid's stem. The prefix "mono-" is used in chemical nomenclature the same way it appears in "monoxide" or "monomer", marking a single unit of the element or group in question.
