4,4,5,5-tetramethyl-2-(2,4,5-trimethylthiophen-3-yl)-1,3,2-dioxaborolane (CAS: 107968-56-5) is a specialized organoboron reagent defined by its pinacol boronate ester structure. Synthesized via borylation of 2-bromo-1,3,5-trimethylbenzene derivatives, it serves as a critical building block in cross-coupling chemistry.
Requires storage under inert atmosphere at temperatures below -20°C to prevent hydrolysis. Strict adherence to PPE protocols is mandatory due to potential skin irritation and respiratory hazards during handling.
