Cas no 2223031-94-3 (5-(4-Tolyl)thiophene-2-boronic acid pinacol ester)
5-(4-Tolyl)thiophene-2-boronic acid pinacol ester is a high-purity boronic ester derivative widely used in Suzuki-Miyaura cross-coupling reactions. Its stable pinacol ester group enhances shelf life and handling convenience, while the thiophene core with a 4-tolyl substituent provides versatility in constructing conjugated systems for organic electronics and pharmaceuticals. The compound exhibits excellent reactivity with aryl and heteroaryl halides, enabling efficient synthesis of complex biaryl structures. Its compatibility with mild reaction conditions and low susceptibility to protodeboronation make it a reliable intermediate for fine chemical synthesis. The product is typically supplied with rigorous quality control to ensure consistent performance in demanding applications.
