(2-Methyl-4-oxo-4H-quinazolin-3-yl)-acetic acid CAS 50844-81-0

Description

The occurrence of (2-Methyl-4-oxo-4H-quinazolin-3-yl)-acetic 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-Methyl-4-oxo-4H-quinazolin-3-yl)-acetic acid (CAS 50844-81-0), molecular formula C11H10N2O3 and molecular weight 218.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2-Methyl-4-oxo-4H-quinazolin-3-yl)-acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
