Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to the presence of multiple reactive sites—aldehyde, hydroxyl, bromo, and chloro groups. The compound is particularly valuable in forming heterocyclic compounds through cyclization reactions. It serves in the preparation of bioactive molecules, including antimicrobial and anti-inflammatory agents. Its halogen substituents allow for cross-coupling reactions, enabling the construction of complex organic frameworks in medicinal chemistry. Also employed in the development of dyes and functional materials where aromatic aldehydes with electron-withdrawing groups are required.
