Chemical Structure

(R)-1-(3,5-bis(trifluoromethyl)phenyl)-N-((S)-1-phenylethyl)ethan-1-amine fumarate CAS 672907-00-5 chemical structure

Description

The occurrence of (R)-1-(3,5-bis(trifluoromethyl)phenyl)-N-((S)-1-phenylethyl)ethan-1-amine fumarate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(R)-1-(3,5-bis(trifluoromethyl)phenyl)-N-((S)-1-phenylethyl)ethan-1-amine fumarate (CAS 672907-00-5), molecular formula C18H17F6NC4H4O4 and molecular weight 477.40 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (R)-1-(3,5-bis(trifluoromethyl)phenyl)-N-((S)-1-phenylethyl)ethan-1-amine fumarate (C18H17F6NC4H4O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
