Chemical Structure
Description
The occurrence of di(2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptyl) 9-oxo-9H-2,7-fluorenedisulphonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
di(2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptyl) 9-oxo-9H-2,7-fluorenedisulphonate (CAS 321579-82-2) is a high-purity analytical reference standard with the molecular formula C27H12F24O7S2 and a molecular weight of 968.47 g/mol.
di(2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptyl) 9-oxo-9H-2,7-fluorenedisulphonate (C27H12F24O7S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), di(2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptyl) 9-oxo-9H-2,7-fluorenedisulphonate 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.
