Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 216.08 g/mol gives 2-(3-Amino-4-bromophenyl)ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(3-Amino-4-bromophenyl)ethanol (CAS 1892991-77-3) is a high-purity analytical reference standard with the molecular formula C8H10BrNO and a molecular weight of 216.08 g/mol.
Structurally, 2-(3-Amino-4-bromophenyl)ethanol (C8H10BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 216.08 g/mol, it falls into the medium-molecular-weight range. 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.
