Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.13 g/mol gives 1-(2-Bromo-4-fluorophenyl)cyclopentanamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-Bromo-4-fluorophenyl)cyclopentanamine (CAS 1704092-27-2) is a high-purity analytical reference standard with the molecular formula C11H13BrFN and a molecular weight of 258.13 g/mol.
Based on its molecular formula C11H13BrFN, 1-(2-Bromo-4-fluorophenyl)cyclopentanamine 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.
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.
