Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals, particularly in the development of nitrogen-containing heterocyclic compounds. Its ethynyl group enables click chemistry applications, especially in coupling reactions such as Sonogashira, making it valuable in material science for constructing conjugated systems. The nitro and amino functionalities allow further derivatization, useful in dye synthesis and functional materials. The trimethylsilyl group enhances stability and solubility in organic solvents, facilitating handling and reaction efficiency.
