Chemical Structure
Description
1-Bromo-2-methyl-5,6-dihydrocyclopenta[c]pyrrol-4(2H)-one (CAS 1555853-56-9) is a high-purity analytical reference standard with the molecular formula C8H8BrNO and a molecular weight of 214.06 g/mol.
Structurally, 1-Bromo-2-methyl-5,6-dihydrocyclopenta[c]pyrrol-4(2H)-one (C8H8BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 214.06 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
