Acetonide is a chemical term used mainly in organic chemistry to describe a compound in which acetone-derived groups form an isopropylidene acetal. In pharmacology and synthesis contexts, it denotes a protecting group or a specific structural motif featuring acetone-derived rings. The term is most often encountered in technical literature rather than everyday speech, and is pronounced with emphasis on the syllable before the -o-ni-de ending.
