Chemical Structure
Description
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.
(1R)-2,2',3,3'-Tetrahydro-6,6'-di-1-pyrenyl-1,1'-spirobi[1H-indene]-7,7'-diol (CAS 1643684-84-7), molecular formula C49H32O2 and molecular weight 652.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1R)-2,2',3,3'-Tetrahydro-6,6'-di-1-pyrenyl-1,1'-spirobi[1H-indene]-7,7'-diol (C49H32O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
