Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) for cardiovascular and central nervous system drugs. It serves as a building block in the development of chiral compounds due to its reactive aldehyde and electron-deficient aromatic ring, enabling selective transformations. Commonly employed in the preparation of antihypertensive agents and serotonin receptor modulators. Also utilized in agrochemical synthesis for creating herbicides and fungicides, where the chloro and methoxy groups contribute to target specificity and stability. Its structural features make it valuable in liquid crystal research and organic electronic materials.
