Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for treating various diseases. It is also employed in organic synthesis to create complex molecules, including agrochemicals and specialty chemicals. Its unique structure makes it valuable in the production of fluorinated compounds, which are often sought after for their enhanced stability and bioactivity. Additionally, it serves as a building block in the manufacture of dyes and pigments, contributing to the color industry. Researchers also utilize it in the development of advanced materials, such as liquid crystals and polymers, due to its reactive aldehyde group and halogen substituents.
