Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and fungicides. It serves as a building block for more complex organic molecules due to the reactive aldehyde group and the substituted aromatic ring. Commonly employed in the development of active ingredients in crop protection products. Also utilized in the preparation of dyes and specialty chemicals where chloro- and methyl-substituted benzaldehyde derivatives are required. Its structure allows for easy functionalization, making it valuable in research and industrial organic synthesis.
