Chemical Structure
Description
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.
2,6-Dimethyl-4-(1-Naphthyl)Pyrylium Hexafluorophosphate (CAS 84282-39-3), molecular formula C17H15OF6P and molecular weight 380.27 g/mol, is a CATO reference standard with documented purity and traceability.
2,6-Dimethyl-4-(1-Naphthyl)Pyrylium Hexafluorophosphate (C17H15OF6P) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, 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.
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.
