Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It serves as a protecting group for phenols due to the stability of the sulfonate ester under various reaction conditions. Commonly employed in the synthesis of liquid crystals and functionalized aromatic compounds. Also utilized in cross-coupling reactions where the methoxyphenyl moiety is introduced into more complex molecular architectures. Its reactivity makes it valuable in the development of agrochemicals and dyes.
