Application

1-(Chloromethyl)-2-fluorobenzene serves as a key building block in pharmaceutical intermediates, particularly for introducing fluorobenzyl motifs into drug candidates. It is employed in Suzuki-Miyaura couplings to create biaryl structures and in nucleophilic displacement reactions for heterocycle synthesis. Researchers also use it to develop fluorinated liquid crystals or agrochemicals due to its balanced reactivity and stability.
