Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. Its reactive acyl chloride group enables it to form amide and ester bonds, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of herbicides and insecticides due to its ability to modify bioactive structures. Also utilized in research settings for introducing the 3-methyl-4-nitrobenzoyl functional group into target compounds, enhancing their stability or biological activity.
