Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It plays a key role in the preparation of certain herbicides and plant growth regulators due to its ability to alkylate various active compounds. Its reactivity makes it valuable in introducing the 2,3-dichlorobenzyl group into larger molecules, enhancing lipophilicity and stability in target applications. Also utilized in the development of specialty chemicals such as dyes and polymer modifiers. Handling requires caution due to its lachrymatory and corrosive properties.
