Chemical Structure
Description
9H-Fluorene-2-sulfonic acid, 9-(dicyclohexylphosphino)-9-[3-(4-sulfophenyl)propyl]-, sulfate (1:1) (CAS 1039775-34-2) is a high-purity analytical reference standard with the molecular formula C34H42O6PS2HO4S and a molecular weight of 738.86 g/mol.
The molecular framework of 9H-Fluorene-2-sulfonic acid, 9-(dicyclohexylphosphino)-9-[3-(4-sulfophenyl)propyl]-, sulfate (1:1) (C34H42O6PS2HO4S) is characterized by a sulfone group, a phosphate ester group, 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), 9H-Fluorene-2-sulfonic acid, 9-(dicyclohexylphosphino)-9-[3-(4-sulfophenyl)propyl]-, sulfate (1:1) 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.
