Chemical Structure
Description
The occurrence of 4-Oxo-3-(prop-2-en-1-yl)-2-sulfanyl-3,4-dihydroquinazoline-7-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Oxo-3-(prop-2-en-1-yl)-2-sulfanyl-3,4-dihydroquinazoline-7-carboxylic acid (CAS 309969-95-7) is a high-purity analytical reference standard with the molecular formula C12H10N2O3S and a molecular weight of 262.28 g/mol.
The molecular framework of 4-Oxo-3-(prop-2-en-1-yl)-2-sulfanyl-3,4-dihydroquinazoline-7-carboxylic acid (C12H10N2O3S) 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).
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.
As a certified reference material (CRM), 4-Oxo-3-(prop-2-en-1-yl)-2-sulfanyl-3,4-dihydroquinazoline-7-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
