Description

Based on its molecular formula C18H20O12P2K, 1014615-46-3 Q9F7QEH36F OXI-4503 dipotassium salt UNII-Q9F7QEH36F 1,2-Benzenediol, 3-methoxy-6-((1Z)-2-(3,4,5-trimethoxyphenyl)ethenyl)-, 1,2-bis(dihydrogen phosphate), potassium salt (1:2) Combretastatin A-1 bis(phosphate) dipotassium salt Combretastatin A1 Diphosphate contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 529.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

1014615-46-3 Q9F7QEH36F OXI-4503 dipotassium salt UNII-Q9F7QEH36F 1,2-Benzenediol, 3-methoxy-6-((1Z)-2-(3,4,5-trimethoxyphenyl)ethenyl)-, 1,2-bis(dihydrogen phosphate), potassium salt (1:2) Combretastatin A-1 bis(phosphate) dipotassium salt Combretastatin A1 Diphosphate (CAS 1014615-46-3) is a high-purity analytical reference standard with the molecular formula C18H20O12P2K and a molecular weight of 529.39 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.
