This chemical is primarily used in organic synthesis as a building block for more complex molecules. Its ethynyl group allows it to participate in reactions like Sonogashira coupling, which is useful in creating carbon-carbon bonds, particularly in the synthesis of pharmaceuticals and organic materials. The trimethylsilyl group acts as a protective group, stabilizing the molecule during reactions and can be easily removed when needed. Additionally, its methoxyphenyl moiety makes it valuable in the development of compounds with potential biological activity, such as antioxidants or anti-inflammatory agents. It is also employed in materials science for the preparation of conjugated polymers and advanced organic electronic materials.
