Chemical Structure
Description
2-(3-Fluoro-4-methoxyphenyl)ethylamine (CAS 458-40-2) is a high-purity analytical reference standard with the molecular formula C9H12FNO and a molecular weight of 169.20 g/mol.
Based on its molecular formula C9H12FNO, 2-(3-Fluoro-4-methoxyphenyl)ethylamine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 169.20 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.
CATO manufactures 2-(3-Fluoro-4-methoxyphenyl)ethylamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
