Product Core Data
tert-Butyl chloroacetate, CAS 107-59-5, C6H11ClO2, Mw 150.60, is a colourless to faint-yellow clear liquid. This hindered halogenated tert-butyl ester unites a tert-butoxycarbonyl group with a chlorine atom, delivering useful steric bulk and high reactivity. It is widely employed as a carboxy-protecting reagent and as a carboxymethylating agent in organic synthesis.
