In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Esters of α, β-dibromopropionic acid, published in 1945, which mentions a compound: 600-05-5, Name is 2,3-Dibromopropionic acid, Molecular C3H4Br2O2, SDS of cas: 600-05-5.
The following esters of α, β-dibromopropionic acid were prepared in 60-5% yields by treating mixtures of the acid with the appropriate alc. and HCl with ice-cooling, followed by standing at room temperature, separation, and washing with water (b60-5, b., d420, nD20 given): Me 129-30°, 203-5°, 1.9333, 1.5127; Et 137-8°, 214-16°, 1.7966, 1.5007; Pr 149-50°, 221-4°, 1.6799, 1.4950; iso-Pr 143-6°, 210-14°, 1.6459, 1.4903; Bu 163-4°, 236-9°, 1.6107, 1.4890; iso-Bu 155-6°, 230-2°, 1.5783, 1.4882; iso-Am 165-9°, 240-4°, 1.5149, 1.4871; allyl 148-50°, 218-21°, 1.7412, 1.5126.
As far as I know, this compound(600-05-5)SDS of cas: 600-05-5 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
