Cas no 1219741-54-4 (4'-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1,1'-biphenyl-2-ol)

4'-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1,1'-biphenyl-2-ol is a boronic ester derivative commonly employed as an intermediate in Suzuki-Miyaura cross-coupling reactions. The presence of the dioxaborolane group enhances stability and handling under ambient conditions, while the biphenyl scaffold with a hydroxyl group offers versatility in further functionalization. This compound is particularly useful in pharmaceutical and materials science research, where precise C-C bond formation is critical. Its high purity and consistent reactivity make it a reliable choice for synthetic applications. The steric hindrance from the tetramethyl groups improves selectivity in coupling reactions, reducing undesired side products. Suitable for use under inert conditions, it is a valuable reagent for advanced organic synthesis.
