Used in the synthesis of dyes and pigments due to its ability to undergo coupling reactions and form colored compounds. It serves as an intermediate in the production of certain pharmaceuticals, particularly in the development of anti-inflammatory and antimicrobial agents. Also employed in the preparation of photographic developers and light-sensitive materials because of its redox properties. Its derivatives are found in some agrochemicals, contributing to the creation of herbicides and plant growth regulators. Additionally, it has limited use in research as a building block for nitroaromatic compounds in organic chemistry.
