Chemical Structure
Description
The molecular framework of 784-90-7 9727AE C12H15N5 N-(4,6,7-Trimethylquinazolin-2-yl)guanidine (C12H15N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).
784-90-7 9727AE C12H15N5 N-(4,6,7-Trimethylquinazolin-2-yl)guanidine (CAS 784-90-7), molecular formula C12H15N5 and molecular weight 229.28 g/mol, is a CATO reference standard with documented purity and traceability.
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.
