Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and analgesic agents. Its structure allows for selective modification in drug design, making it valuable in creating compounds with improved metabolic stability and bioavailability. Commonly employed in research settings for constructing complex organic molecules where a protected carboxylic acid and ether linkage are required. Also utilized in the preparation of prodrugs due to the presence of the tert-butyl ester group, which can be easily cleaved under physiological conditions to release the active drug moiety.
