Chemical Structure

4-amino-2-methylquinazoline-8-carboxylic acid CAS 1268520-96-2 chemical structure

Description

The occurrence of 4-amino-2-methylquinazoline-8-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.

CATO supplies 4-amino-2-methylquinazoline-8-carboxylic acid (CAS 1268520-96-2), a certified reference material (molecular formula C10H19N3O2, MW 213.28 g/mol) for analytical method development and quality control.

Structurally, 4-amino-2-methylquinazoline-8-carboxylic acid (C10H19N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 213.28 g/mol, it falls into the medium-molecular-weight range. 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).

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.
