The occurrence of (4-Chloro-3-fluorophenyl)(4-(pyrrolidin-1-ylmethyl)phenyl)methanone is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Chloro-3-fluorophenyl)(4-(pyrrolidin-1-ylmethyl)phenyl)methanone (CAS 898776-57-3), molecular formula C18H17ClFNO and molecular weight 317.79 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H17ClFNO, (4-Chloro-3-fluorophenyl)(4-(pyrrolidin-1-ylmethyl)phenyl)methanone contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 317.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
