Chemical Structure
Description
3-(Chloromethyl)cyclopentan-1-one (C6H9ClO) contains a hydroxyl group, an ether linkage, chlorine 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.
3-(Chloromethyl)cyclopentan-1-one (CAS 66980-41-4), molecular formula C6H9ClO and molecular weight 132.59 g/mol, is a CATO reference standard with documented purity and traceability.
