Chemical Structure
Description
The molecular framework of 65740-56-9 5-Amino-6-methoxy-1,3-dihydro-2H-benzimidazol-2-one DTXSID60589902 (C8H15N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
65740-56-9 5-Amino-6-methoxy-1,3-dihydro-2H-benzimidazol-2-one DTXSID60589902 (CAS 65740-56-9), molecular formula C8H15N3O2 and molecular weight 185.22 g/mol, is a CATO reference standard with documented purity and traceability.
