Product Name:2-(Bis(tert-butoxycarbonyl)amino)-5-bromopyridin-3-yl 4-methylbenzenesulfonate
English Name:2-(Bis(tert-butoxycarbonyl)amino)-5-bromopyridin-3-yl 4-methylbenzenesulfonate
CAS No.:1803573-21-8
Aliases:Di-tert-butyl (5-bromo-3-tosyloxypyridin-2-yl)iminodicarbonate, 5-Bromo-2-(bis(tert-butoxycarbonyl)amino)pyridin-3-yl 4-methylbenzenesulfonate
Molecular Formula:C22H27BrN2O7S
Physical Properties:Boiling point 592.6 ± 60.0 °C; density 1.408 ± 0.06 g/cm³; acidity coefficient (pKa) -2.81 ± 0.10. It appears as an off-white to light yellow powder at room temperature, soluble in dichloromethane, chloroform, ethyl acetate and other organic solvents, insoluble in water.
Uses:This product is a pharmaceutical and chemical intermediate, mainly used in the synthesis of multi-substituted pyridine compounds. It contains a bis-Boc-protected amino group and an active sulfonate ester group, and can serve as a key building block for structural modification of drug molecules and preparation of fine chemicals, widely used in pharmaceutical R&D and chemical production.
Technical Specifications:
