Used primarily in organic synthesis, especially in the preparation of anthracene-based polymers and fluorescent compounds. Its reactive chloromethyl group allows for easy attachment to other molecules, making it valuable in the development of photoactive materials and organic semiconductors. Commonly employed in the synthesis of dendrimers and cross-linked resins for optoelectronic applications. Also serves as a precursor in the production of dyes and sensors due to its strong fluorescence properties.
