Isoamyl isovalerate

At a glance

A fruity ester with an apple character carrying a slightly sharp, cheesy edge typical of isovalerate esters. It is used by perfumers as one of many aroma-chemical building blocks that combine to form a fragrance's overall accord, rather than being worn as a scent on its own.
