Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of pharmaceuticals and agrochemicals. Its chloromethyl group readily undergoes nucleophilic substitution, enabling the introduction of the 4-(methylsulfonyl)benzyl moiety into target molecules. It is particularly valuable in the synthesis of sulfone-containing bioactive compounds. Additionally, it can act as a building block in the development of functional materials and specialty chemicals where sulfonyl groups impart desired polarity or stability.
