Chemical Structure
Description
The occurrence of 4-(3-Bromo-4-fluorophenyl)piperidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(3-Bromo-4-fluorophenyl)piperidine (CAS 1260868-73-2), molecular formula C11H13BrFN and molecular weight 258.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H13BrFN, 4-(3-Bromo-4-fluorophenyl)piperidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.13 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.
As a certified reference material (CRM), 4-(3-Bromo-4-fluorophenyl)piperidine 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.
