Chemical Structure
Description
The molecular framework of 1-((1R,2R)-2-Amino-1,2-diphenylethyl)-3-(3,5-bis(trifluoromethyl)phenyl)thiourea (C23H19F6N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-((1R,2R)-2-Amino-1,2-diphenylethyl)-3-(3,5-bis(trifluoromethyl)phenyl)thiourea (CAS 1088705-53-6), molecular formula C23H19F6N3S and molecular weight 483.47 g/mol, is a CATO reference standard with documented purity and traceability.
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.
