Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of sulfur-based dyes for textiles. Also serves as a building block in agrochemicals for developing herbicides and fungicides. Its sulfone-aniline structure makes it valuable in pharmaceutical research, especially in creating compounds with anti-inflammatory and antimicrobial activity. Additionally, it is employed in the development of specialty polymers and photoresists due to its thermal stability and electron-withdrawing properties.
