Furfural, also known as furan-2-aldehyde or 2-furaldehyde, is a versatile organic compound with a distinct almond-like odor. It belongs to the family of heterocyclic compounds, specifically containing a furan ring with an aldehyde functional group. Furfural is primarily derived from agricultural residues such as corn cobs, wheat straw, and sawdust through acid-catalyzed dehydration of pentoses. Its industrial applications are extensive, spanning from solvent use in petroleum refining to the synthesis of resins, pharmaceuticals, and pesticides. Due to its unique chemical structure, furfural exhibits a range of reactive properties, making it a key intermediate in various chemical processes.
