Methyl 2-bromomethyl-3-nitrobenzoate is a white or light yellow solid under normal temperature and pressure. It is insoluble in water but soluble in alcoholic organic solvents. It is an organic ester derivative that can be used as an organic synthesis intermediate and a raw material for pharmaceutical chemical synthesis. It is a crucial synthesis intermediate for the drug molecule lenalidomide. Lenalidomide is an antineoplastic drug. The ester group and benzyl bromide unit in the Methyl 2-bromomethyl-3-nitrobenzoate structure are easily convertible functional groups. Its structure contains a strong electron-attracting nitro group and an easily leaving bromine atom. The nitro group is a strong electron-withdrawing group that can increase the reactivity of molecules through conjugation effects and electron attraction. Due to these properties, it has wide applications in organic synthesis transformations.
