Chemical Structure

(R)-2,2',3,3'-Tetrahydro-1,1'-spirobi[indene]-7,7'-diyl bis(trifluoromethanesulfonate) CAS 528521-72-4 chemical structure

Description

The occurrence of (R)-2,2',3,3'-Tetrahydro-1,1'-spirobi[indene]-7,7'-diyl bis(trifluoromethanesulfonate) is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(R)-2,2',3,3'-Tetrahydro-1,1'-spirobi[indene]-7,7'-diyl bis(trifluoromethanesulfonate) (CAS 528521-72-4) is a high-purity analytical reference standard with the molecular formula C19H14F6O6S2 and a molecular weight of 516.43 g/mol.

The molecular framework of (R)-2,2',3,3'-Tetrahydro-1,1'-spirobi[indene]-7,7'-diyl bis(trifluoromethanesulfonate) (C19H14F6O6S2) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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.
