Used as an intermediate in organic synthesis, particularly in the preparation of spiro-based conjugated materials for optoelectronic devices. Its rigid spirocyclic structure enhances thermal stability and influences molecular packing in thin films, making it valuable in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). The bromine and hydroxyl functional groups allow for further derivatization through cross-coupling reactions or esterification, enabling fine-tuning of electronic properties. Also employed in the synthesis of ligands for metal-organic complexes used in catalysis or luminescent materials.
