Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [2-(3,4-dimethoxyphenyl)ethyl](2-phenylethyl)amine hydrochloride.
[2-(3,4-dimethoxyphenyl)ethyl](2-phenylethyl)amine hydrochloride (CAS 35589-98-1), molecular formula C18H23NO2HCl and molecular weight 321.84 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [2-(3,4-dimethoxyphenyl)ethyl](2-phenylethyl)amine hydrochloride (C18H23NO2HCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
