Chemical Structure
Description
The molecular framework of N-(6-Oxo-6,9-dihydro-1H-purin-2-yl)benzamide (C12H9N5O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
N-(6-Oxo-6,9-dihydro-1H-purin-2-yl)benzamide (CAS 21323-87-5), molecular formula C12H9N5O2 and molecular weight 255.23 g/mol, is a CATO reference standard with documented purity and traceability.
