Used as a key intermediate in organic synthesis, particularly in the preparation of advanced materials and pharmaceuticals. Its ethynyl group enables coupling reactions, such as Sonogashira cross-coupling, allowing the construction of conjugated systems important in electronic materials and liquid crystals. The trimethylsilyl group acts as a protecting group or solubility enhancer in synthetic pathways. The presence of the trifluoromethylphenyl moiety contributes electron-withdrawing properties, enhancing stability and influencing electronic characteristics in final products. Commonly applied in research settings for developing fluorinated compounds with potential biological activity or use in optoelectronic devices.
