Chemical Structure
Description
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.
Thiopyrylium, 4-[4-(dimethylamino)phenyl]-2,6-diphenyl-, hexafluorophosphate(1-) (CAS 33034-18-3), molecular formula C25H22NSF6P and molecular weight 513.48 g/mol, is a CATO reference standard with documented purity and traceability.
Thiopyrylium, 4-[4-(dimethylamino)phenyl]-2,6-diphenyl-, hexafluorophosphate(1-) (C25H22NSF6P) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, organophosphorus functionality, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
