Used primarily as an intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals. Its reactive acid chloride groups allow for easy attachment to other molecules, making it valuable in constructing complex organic compounds. Commonly employed in the preparation of heterocyclic compounds and active esters. Also utilized in the development of specialty polymers and photoactive materials due to the presence of the nitro group, which can influence electronic properties. Suitable for use in controlled reactions where selective acylation is required.
