Used as a reagent in cross-coupling reactions, particularly in the synthesis of biaryl compounds through Suzuki-Miyaura coupling. The trifluoroborate group offers enhanced stability compared to boronic acids, allowing for easier handling and storage. Its thiophene-based structure makes it valuable in the preparation of conjugated organic materials, including semiconductors and fluorescent dyes. Commonly applied in pharmaceutical and agrochemical research where methylthiophene motifs are present in bioactive molecules. Also employed in materials science for constructing π-conjugated systems used in organic electronics.
