Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its reactive aldehyde group and fluorinated benzyl structure, which enhances binding selectivity and metabolic stability. Commonly employed in the preparation of tyrosine kinase inhibitors and other biologically active molecules. Also utilized in the fabrication of fluorescent probes and sensors owing to its favorable electronic properties.
