Chemical Structure
Description
2,2'-(9,9-Dioctyl-9H-fluorene-2,7-diyl)dithiophene (C37H46S2) contains sulfur-containing functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
2,2'-(9,9-Dioctyl-9H-fluorene-2,7-diyl)dithiophene (CAS 338469-45-7), molecular formula C37H46S2 and molecular weight 554.89 g/mol, is a CATO reference standard with documented purity and traceability.
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.
