(S)-[2,3':1',1'':3'',2'''-Quaternaphthalene]-2',2''-diol CAS 863659-89-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-[2,3':1',1'':3'',2'''-Quaternaphthalene]-2',2''-diol.

(S)-[2,3':1',1'':3'',2'''-Quaternaphthalene]-2',2''-diol (CAS 863659-89-6), molecular formula C40H26O2 and molecular weight 538.63 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-[2,3':1',1'':3'',2'''-Quaternaphthalene]-2',2''-diol (C40H26O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 538.63 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
