Product Name:Zinc, bromo[2-(1,1-dimethylethoxy)-2-oxoethyl]-
English Name:Zinc, bromo[2-(1,1-dimethylethoxy)-2-oxoethyl]-
CAS No.:51656-70-3
Aliases:Bromo[2-(tert-butoxy)-2-oxoethyl]zinc, 2-(tert-Butoxy)-2-oxoethylzinc bromide
Molecular Formula:C6H11BrO2Zn
Physical Properties:Appears as a light yellow to brown liquid, commonly supplied as a tetrahydrofuran solution. Sensitive to air and moisture; should be stored under inert gas at low temperature (2-8°C). Density is approximately 0.95 g/mL (solution), with a low flash point and flammability.
Uses:Used as an organozinc reagent in transition-metal-catalyzed Negishi cross-coupling reactions for carbon-carbon bond formation. Also serves as a nucleophilic alkylating agent to introduce the tert-butoxycarbonylmethyl (Boc-CH2-) group into organic molecules, applicable in pharmaceutical and fine chemical synthesis.
Technical Specifications:
Purity: ≥95% (GC titration)
Molecular weight: 260.35
Concentration: commonly 0.5 mol/L in tetrahydrofuran
Storage: keep at 2-8°C under nitrogen, protected from light and sealed
Package sizes: customizable (e.g., 50mL, 100mL, 500mL)
