Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. The aldehyde group allows for further functionalization through reactions such as Wittig, Grignard additions, or reductive amination, while the ester group can be hydrolyzed to yield carboxylic acid derivatives. Its phenoxy backbone makes it suitable for constructing biologically active molecules, including drug candidates targeting inflammation, CNS disorders, or metabolic diseases. Commonly employed in multi-step syntheses where selective protection and deprotection strategies are required due to the presence of orthogonal functional groups.
