Used as a key intermediate in the synthesis of fluorinated organic compounds, particularly in pharmaceuticals and agrochemicals where the fluorine atom enhances metabolic stability and bioavailability. It serves in the preparation of fluorescent dyes and optical brighteners due to its aromatic structure capable of participating in conjugated systems. Also employed in coordination chemistry as a building block for metal-organic frameworks (MOFs), where its carboxylic acid groups facilitate metal ion binding, enabling the design of porous materials for gas storage or catalysis. Its fluorinated moiety can influence crystal packing and polarity, making it useful in materials science for tuning physical properties.
