Compared with other compounds in its class, the molecular weight of 487.34 g/mol gives 6-Benzamido-9-benzyl-7-ethyl-9H-purin-7-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Benzamido-9-benzyl-7-ethyl-9H-purin-7-ium iodide (CAS 77868-53-2), a certified reference material (molecular formula C21H22N5OI, MW 487.34 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H22N5OI, 6-Benzamido-9-benzyl-7-ethyl-9H-purin-7-ium iodide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 487.34 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).
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.
