Chemical Structure
Description
Based on its molecular formula C26H23O4BF3F, 2,4,6-tris(4-methoxyphenyl)pyrylium tetrafluoroborate 580-34-7 contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 486.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2,4,6-tris(4-methoxyphenyl)pyrylium tetrafluoroborate 580-34-7 (CAS 580-34-7) is a high-purity analytical reference standard with the molecular formula C26H23O4BF3F and a molecular weight of 486.27 g/mol.
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.
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.
