| Application: | Butyraldehyde can be used as a reactant in the:• Reductive amination of various nitroarene derivatives to synthesize mono-N-alkylated aniline derivatives. • Ionic liquid-catalyzed Knoevenagel condensation with active methylene compounds to synthesize substituted electrophilic alkenes. • NiCl2-catalyzed synthesis of α-aminonitriles by reacting with amines and trimethylsilyl cyanides. |
| General description: | Butyraldehyde, also known as Butanal, is an aliphatic aldehyde, that is commonly used as a versatile building block in various organic reactions, such as in the synthesis of diverse C4–C8 alcohols, esters, amines, and carboxylic acids. |
