(S)-5-Guanidino-2-((((6-(6-oxo-1H-purin-9(6H)-yl)hexyl)oxy)carbonyl)amino)pentanoic acid (CAS 128554-80-3) is a high-purity analytical reference standard with the molecular formula C18H28N8O5 and a molecular weight of 436.47 g/mol.

Structurally, (S)-5-Guanidino-2-((((6-(6-oxo-1H-purin-9(6H)-yl)hexyl)oxy)carbonyl)amino)pentanoic acid (C18H28N8O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 436.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.
