Chemical Structure
Description
2-Iodocyclopent-2-enone (C5H5IO) contains a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-Iodocyclopent-2-enone (CAS 33948-35-5), molecular formula C5H5IO and molecular weight 208.00 g/mol, is a CATO reference standard with documented purity and traceability.
