Compared with other compounds in its class, the molecular weight of 228.21 g/mol gives 2-[4-(trifluoromethyl)phenyl]cyclopentan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-[4-(trifluoromethyl)phenyl]cyclopentan-1-one (CAS 1253111-75-9), molecular formula C12H11F3O and molecular weight 228.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-[4-(trifluoromethyl)phenyl]cyclopentan-1-one (C12H11F3O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 228.21 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
