Used primarily as a key intermediate in the synthesis of herbicidal compounds, particularly in the production of aryloxyalkanoic acid derivatives. Its chlorinated biphenyl structure makes it valuable in agrochemical manufacturing for developing selective herbicides that target broadleaf weeds in cereal crops. The carboxylic acid functional group allows for easy derivatization, enabling incorporation into larger active molecules. It is also utilized in research settings for designing novel biologically active compounds due to its rigid biphenyl scaffold and halogen substitution pattern, which can influence binding to biological targets.
