Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of long-chain alkylated aromatic derivatives. Its sulfonate ester group acts as a good leaving group, facilitating nucleophilic substitution reactions. It is employed in the development of surfactants, lubricants, and specialty chemicals where a long hydrophobic chain is required. The tosylate functionality allows for chain extension or functionalization in pharmaceutical and polymer research. Due to its stability and reactivity profile, it is also utilized in alkylation processes and in the synthesis of complex molecules requiring selective transformations.
