A clear, highly flammable liquid used in the production of synthetic materials and resins.
Butyraldehyde is commonly used in the manufacture of plastics and other chemical products.
Butyraldehyde is formed from "butyr-" (from Latin *butyrum*, meaning butter) and "aldehyde" (from the German *Aldehyd*, which is a contraction of *Alkohol dehydrogenatum*, meaning dehydrogenated alcohol). The term refers to a compound related to butter and characterized by its aldehyde functional group.
Think of 'butter' ('butyr-') to remember that butyraldehyde is related to the smell of butter, combined with the idea of a 'dehydrogenated alcohol' ('aldehyde').
