Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in reactions where a sulfonyl group is needed for further functionalization. Its methoxy and methylsulfonyl substituents make it suitable for use in electrophilic aromatic substitution and cross-coupling reactions. It also serves in the development of herbicides and fungicides due to the stability and reactivity provided by the sulfonyl moiety. Additionally, it can act as a building block in the preparation of sulfone-based polymers with enhanced thermal and oxidative stability.
