1-Chloro-3-(4-fluorophenyl)propan-2-one CAS 303967-88-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Chloro-3-(4-fluorophenyl)propan-2-one.

1-Chloro-3-(4-fluorophenyl)propan-2-one (CAS 303967-88-6), molecular formula C9H8ClFO and molecular weight 186.61 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H8ClFO, 1-Chloro-3-(4-fluorophenyl)propan-2-one contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
