Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(R)-1-(2-Bromo-4-fluorophenyl)ethan-1-amine (CAS 1228557-09-2) is a high-purity analytical reference standard with the molecular formula C8H9BrFN and a molecular weight of 218.07 g/mol.
Based on its molecular formula C8H9BrFN, (R)-1-(2-Bromo-4-fluorophenyl)ethan-1-amine 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 218.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
