Application：

9H-Fluorene-9-carboxylic acid is primarily used as a key intermediate in pharmaceutical synthesis, particularly for the production of antimalarial drugs, antiviral agents, and other bioactive compounds featuring the fluorene scaffold. It also serves as a valuable building block for functional polymers, liquid crystal materials, and organic light-emitting diodes (OLEDs) due to its rigid planar structure and excellent charge transport properties. Additionally, it is widely employed in the synthesis of fluorescent probes, photosensitizers, and as a protecting group reagent in peptide chemistry.
