Widely used as an intermediate in the synthesis of agrochemicals, particularly herbicides and fungicides, due to its reactive aldehyde group and chlorine substituents that facilitate further chemical modifications. It plays a key role in the production of certain pharmaceuticals, where it serves as a building block for active ingredients with anti-inflammatory or antimicrobial properties. Its aromatic structure with electron-withdrawing chlorine atoms makes it suitable for use in organic reactions such as condensations and nucleophilic substitutions. Additionally, it is employed in the development of dyes and specialty chemicals where halogenated aromatic aldehydes are required for specific color or stability characteristics.
