2,4-Diamino-5,6,7,8-tetrahydro-6-quinazolinecarboxylic Acid (CAS 6974-25-0) is a high-purity analytical reference standard with the molecular formula C9H12N4O2 and a molecular weight of 208.22 g/mol.
The molecular framework of 2,4-Diamino-5,6,7,8-tetrahydro-6-quinazolinecarboxylic Acid (C9H12N4O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
