Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[1-(4-chlorophenyl)cyclobutyl]ethan-1-one.
1-[1-(4-chlorophenyl)cyclobutyl]ethan-1-one (CAS 84467-20-9) is a high-purity analytical reference standard with the molecular formula C12H13ClO and a molecular weight of 208.68 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-[1-(4-chlorophenyl)cyclobutyl]ethan-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.68 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.
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.
As a certified reference material (CRM), 1-[1-(4-chlorophenyl)cyclobutyl]ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
