Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. It serves as a ligand in coordination chemistry, forming complexes with transition metals that are employed as catalysts in cross-coupling reactions. Also utilized in the preparation of functional materials for optoelectronic devices due to its ability to modulate electronic properties in metal-organic frameworks. Its chloro-substituent allows for further functionalization, making it valuable in modular synthetic strategies.
