Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of fluorinated and halogenated aromatic compounds. Its functionalized aromatic ring allows for selective cross-coupling reactions, making it valuable in the production of active pharmaceutical ingredients (APIs) where specific substitution patterns enhance biological activity. Commonly employed in the preparation of kinase inhibitors and other bioactive molecules in medicinal chemistry. Also utilized in the synthesis of crop protection agents due to the enhanced stability and reactivity imparted by the halogen substituents. The aldehyde group further enables derivatization through reactions such as condensations and imine formations, facilitating the construction of more complex molecular structures.
