1-(2-(Pyrrolidin-1-yl)ethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole（Cat No.:L038203）is a boron-containing heterocyclic compound widely used as a boronate ester intermediate in cross-coupling reactions, particularly Suzuki-Miyaura couplings. It features a pyrazole ring substituted with a pyrrolidinylethyl chain at the 1-position and a pinacol boronate ester at the 4-position, enabling selective C–C bond formation. The compound is valued for its stability, ease of handling, and compatibility with mild reaction conditions. It serves as a key building block in the synthesis of drug candidates, agrochemicals, and functional materials requiring complex nitrogen- and boron-containing heterocycles.
