Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. It serves as a protected form of 3-aminophenol, allowing selective reactions at other functional sites during multi-step syntheses. Commonly employed in the development of analgesics and anti-inflammatory agents due to its structural similarity to acetaminophen. Also utilized in the preparation of dyes and UV absorbers for polymers, offering stability against photodegradation. Its acetyl-protected amine and phenolic groups make it valuable in peptide synthesis and in the creation of specialty esters for cosmetic formulations.
