Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in reactions where the alkyne group can undergo click chemistry or coupling reactions. Its chloro and propargyloxy functional groups allow for selective modifications, making it valuable in building complex organic molecules. Commonly employed in the development of liquid crystals and functional materials due to its rigid aromatic structure and reactive handles. Also utilized in research settings for labeling biomolecules through copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions.
