Chemical Structure
Description
The occurrence of 2,4,6-Triphenylpyrylium trifluoromethanesulfonate is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4,6-Triphenylpyrylium trifluoromethanesulfonate (CAS 70962-62-8), molecular formula C23H17OCF3O3S and molecular weight 458.45 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2,4,6-Triphenylpyrylium trifluoromethanesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 458.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2,4,6-Triphenylpyrylium trifluoromethanesulfonate 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.
