Frequent Uses

Organic synthesis
Butyraldehyde undergoes reactions typical of alkyl aldehydes, and these define many of the uses of this compound. Important reactions include hydrogenation to the alcohol, oxidation to the acid, and base-catalyzed condensation.

Paints and varnishes
Butyraldehyde is a component in the two-step synthesis of trimethylolpropane, which is used for the production of alkyd resins. Alkyds are then in turn used for paints, varnishes and in moulds for casting. They are the dominant resin or binder in most commercial oil-based coatings.

Plasticisers
In the presence of a base, two equivalents of butyraldehyde undergo aldol condensation to give 2-ethylhexenal. This unsaturated aldehyde is then partially hydrogenated to form 2-ethylhexanal, a precursor to plasticisers such as bis(2-ethylhexyl) phthalate.
