Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves in the production of certain analgesics and anti-inflammatory drugs due to its structural similarity to acetanilide derivatives known for such activity. Also employed in the development of dyes and pigments, where it contributes to color stability and lightfastness. Its role as a protecting group in organic synthesis allows selective reactions in complex molecule assembly. Limited use in polymer stabilization has been noted, particularly in systems requiring resistance to thermal degradation.
