Chemical Structure
Description
1-(4-Methoxyphenyl)ethylamine Hydrochloride (CAS 90642-63-0), molecular formula C9H13NOHCl and molecular weight 187.67 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H13NOHCl, 1-(4-Methoxyphenyl)ethylamine Hydrochloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 187.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
