This compound is primarily used in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura reactions. It serves as a key intermediate for constructing complex molecules, especially in the development of pharmaceuticals and agrochemicals. Its deuterated form (d8) makes it valuable in isotopic labeling studies, aiding in the tracing and analysis of reaction mechanisms or metabolic pathways. Additionally, it is utilized in the synthesis of advanced materials, including organic semiconductors and polymers, due to its ability to introduce thiophene-based structures, which are essential for electronic and optoelectronic applications.
