Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated drug candidates. Its aldehyde group allows for further functionalization through reactions such as reductive amination or Wittig reactions, enabling the construction of complex molecules. The tert-butyl ester group provides stability during synthesis and can be easily deprotected under mild acidic conditions when needed. Commonly employed in medicinal chemistry for the preparation of bioactive compounds targeting central nervous system disorders and inflammatory diseases. Also utilized in the preparation of agrochemicals and specialty materials where fluorine substitution enhances performance.
