This chemical is primarily used in organic synthesis as a building block for more complex molecules. It is particularly valuable in the preparation of pyridine derivatives, which are important in pharmaceuticals and agrochemicals. The trimethylsilyl group acts as a protecting group for the ethynyl functionality, allowing selective reactions to occur at other sites of the molecule. Additionally, it is employed in the development of materials for organic electronics, such as organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs), due to its ability to modify electronic properties. Its ethynyl group also makes it a useful intermediate in click chemistry reactions, facilitating the creation of diverse molecular architectures.
