Used primarily as an intermediate in the synthesis of dyes and pigments, particularly in the production of disperse dyes for polyester and related textiles. It plays a key role in introducing nitro-substituted aromatic structures that enhance color fastness and thermal stability. Also employed in the preparation of photoactive compounds and in some agrochemical syntheses due to its reactivity as an acylating agent. Its nitro group allows for further functionalization, making it valuable in multi-step organic synthesis.
