Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its ethynyl group enables efficient coupling reactions in organic synthesis, especially in Sonogashira cross-coupling, allowing for the construction of complex molecular architectures. The trimethylsilyl group enhances stability and solubility during reaction processes, making it valuable in multi-step synthetic routes. Additionally, it serves in agrochemical research for designing novel bioactive molecules with improved efficacy and selectivity.
