2-(4-Morpholino)ethyl 2-Bromoisobutyrate (CAS 627106-74-5) has a molecular formula of C??H??BrNO? and molecular weight of 280.16 g/mol, consisting of a 2-(4-morpholino)ethyl ester group and a brominated isobutyrate moiety (BrC(CH?)?COO-). As a functional bromoester, it is a key initiator/precursor in controlled radical polymerization (e.g., ATRP) and pharmaceutical synthesis. It requires sealed, cool, dry storage to avoid hydrolysis of the ester group, and handling with care due to the bromine atom, ensuring reactivity and stability for synthetic applications.
