Chemical Structure
Description
Based on its molecular formula C10H8BrN, 1-Bromonaphthalen-2-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-Bromonaphthalen-2-amine (CAS 20191-75-7) is a high-purity analytical reference standard with the molecular formula C10H8BrN and a molecular weight of 222.08 g/mol.
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.
