Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly naproxen and related derivatives. Its protected amine and acetyl functionalities allow selective chemical transformations during multi-step organic syntheses. Commonly employed in pharmaceutical research for developing analgesic and antipyretic agents. Also utilized in the preparation of naphthalene-based prodrugs due to its stability and controlled reactivity under mild hydrolytic conditions.
