Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes due to its ability to undergo diazotization and coupling reactions. It also serves in the manufacture of certain pharmaceuticals and agrochemicals where nitrophenol derivatives are required. Its methyl and nitro functional groups allow for selective chemical modifications, making it valuable in organic synthesis pathways. Additionally, it has been explored in the development of sensors and analytical reagents for detecting specific metal ions.
