Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where the aldehyde and amine functional groups allow for further derivatization. Commonly employed in the preparation of heterocyclic compounds, including quinazolines and other nitrogen-containing rings, which are prevalent in medicinal chemistry. Also utilized in dye synthesis and organic synthesis research due to its bifunctional reactivity, enabling Schiff base formation or reduction reactions to produce amino alcohols or aminomethyl derivatives.
