Description
Compared with other compounds in its class, the molecular weight of 280.30 g/mol gives 3-(2-Methoxyethyl)-4-oxo-2-thioxo-1,2,3,4-tetrahydroquinazoline-7-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(2-Methoxyethyl)-4-oxo-2-thioxo-1,2,3,4-tetrahydroquinazoline-7-carboxylic acid (CAS 361150-40-5), a certified reference material (molecular formula C12H12N2O4S, MW 280.30 g/mol) for analytical method development and quality control.
The molecular framework of 3-(2-Methoxyethyl)-4-oxo-2-thioxo-1,2,3,4-tetrahydroquinazoline-7-carboxylic acid (C12H12N2O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 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.
