Chen, Doris’s team published research in Tetrahedron in 2020 | CAS: 3395-91-3

Methyl 3-bromopropanoate(cas: 3395-91-3) belongs to bromides. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents.COA of Formula: C4H7BrO2
