Chemical Structure
Description
The occurrence of 2-(2-chlorophenyl)cyclopentan-1-one is closely related to a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2-chlorophenyl)cyclopentan-1-one (CAS 1242029-81-7), molecular formula C11H17ClO and molecular weight 200.71 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, 2-(2-chlorophenyl)cyclopentan-1-one is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 200.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
