Used in biochemical research as a precursor or intermediate in the synthesis of biotin analogs. Commonly employed in labeling and detection systems where biotin-streptavidin interactions are utilized, such as ELISA, immunohistochemistry, and molecular probes. Due to its structural similarity to biotin, it can be incorporated into biomolecules for affinity-based assays without active vitamin functionality. Also used in the development of biosensors and drug delivery systems where controlled binding and release are required.
