(1S)-3,3'-Bis(3,5-bis(trifluoromethyl)phenyl)-[1,1'-binaphthalene]-2,2'-disulfonic acid CAS 1216890-08-2 chemical structure

Description

The occurrence of (1S)-3,3'-Bis(3,5-bis(trifluoromethyl)phenyl)-[1,1'-binaphthalene]-2,2'-disulfonic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (1S)-3,3'-Bis(3,5-bis(trifluoromethyl)phenyl)-[1,1'-binaphthalene]-2,2'-disulfonic acid (CAS 1216890-08-2), a certified reference material (molecular formula C36H18F12O6S2, MW 838.64 g/mol) for analytical method development and quality control.

The molecular framework of (1S)-3,3'-Bis(3,5-bis(trifluoromethyl)phenyl)-[1,1'-binaphthalene]-2,2'-disulfonic acid (C36H18F12O6S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
