γ-Hydroxybutyraldehyde, also referred to as GHBAL, γ-hydroxybutaldehyde or γ-hydroxybutanal, is a chemical intermediate in the biosynthesis of the neurotransmitter γ-hydroxybutyric acid (GHB) from 1,4-butanediol (1,4-BD). Like 1,4-BD, it also behaves as a prodrug to GHB when taken exogenously. However, as with all aliphatic aldehydes, γ-hydroxybutaldehyde is caustic and is strong-smelling and foul-tasting; thus, actual ingestion of this compound is likely to be unpleasant and result in severe nausea and vomiting.
