Used in organic synthesis as a building block for more complex molecules, particularly in the development of pharmaceuticals and agrochemicals. It serves as a precursor in the creation of compounds with potential biological activity, such as anti-inflammatory or antimicrobial agents. Its nitro group makes it a valuable intermediate in reactions involving reduction or further functionalization. Additionally, it is employed in research settings to study indole derivatives and their interactions in various chemical and biological systems. Its applications extend to dye chemistry, where it may be used in the synthesis of specialized colorants.
