(7S,9S)-9-Acetyl-7-[(2R,3R,4R,5S,6S)-3-Fluoro-4,5-Dihydroxy-6-Methyloxan-2-Yl]Oxy-6,9,11-Trihydroxy-4-Methoxy-8,10-Dihydro-7H-Tetracene-5,12-Dione CAS 103946-11-8 chemical structure

Description

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.

(7S,9S)-9-Acetyl-7-[(2R,3R,4R,5S,6S)-3-Fluoro-4,5-Dihydroxy-6-Methyloxan-2-Yl]Oxy-6,9,11-Trihydroxy-4-Methoxy-8,10-Dihydro-7H-Tetracene-5,12-Dione (CAS 103946-11-8) is a high-purity analytical reference standard with the molecular formula C27H27FO11 and a molecular weight of 546.50 g/mol.

The molecular framework of (7S,9S)-9-Acetyl-7-[(2R,3R,4R,5S,6S)-3-Fluoro-4,5-Dihydroxy-6-Methyloxan-2-Yl]Oxy-6,9,11-Trihydroxy-4-Methoxy-8,10-Dihydro-7H-Tetracene-5,12-Dione (C27H27FO11) is characterized by 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).

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.
