Chemical Structure
Description
The occurrence of 2-Amino-4-oxo-3,4,5,6,7,8-hexahydroquinazoline-6-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Amino-4-oxo-3,4,5,6,7,8-hexahydroquinazoline-6-carboxylic acid (CAS 5429-55-0), molecular formula C9H11N3O3 and molecular weight 209.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Amino-4-oxo-3,4,5,6,7,8-hexahydroquinazoline-6-carboxylic acid (C9H11N3O3) 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.
