118555-84-3 [1,2'-Bianthracene]-9,9',10,10'-tetrone,1',4,5,8'-tetrahydroxy-2,3'-dimethoxy-6',7-dimethyl-, (1R)- (9CI) (CAS 118555-84-3) is a high-purity analytical reference standard with the molecular formula C32H22O10 and a molecular weight of 566.51 g/mol.
The molecular framework of 118555-84-3 [1,2'-Bianthracene]-9,9',10,10'-tetrone,1',4,5,8'-tetrahydroxy-2,3'-dimethoxy-6',7-dimethyl-, (1R)- (9CI) (C32H22O10) 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 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.
As a certified reference material (CRM), 118555-84-3 [1,2'-Bianthracene]-9,9',10,10'-tetrone,1',4,5,8'-tetrahydroxy-2,3'-dimethoxy-6',7-dimethyl-, (1R)- (9CI) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
