2-((1-(2-Hydroxyethyl)-2-oxo-1,2,5,6,7,8-hexahydroquinazolin-4-yl)thio)-N-(thiazol-2-yl)acetamide CAS 899743-04-5

Description

2-((1-(2-Hydroxyethyl)-2-oxo-1,2,5,6,7,8-hexahydroquinazolin-4-yl)thio)-N-(thiazol-2-yl)acetamide (CAS 899743-04-5), molecular formula C15H18N4O3S2 and molecular weight 366.46 g/mol, is a CATO reference standard with documented purity and traceability.

2-((1-(2-Hydroxyethyl)-2-oxo-1,2,5,6,7,8-hexahydroquinazolin-4-yl)thio)-N-(thiazol-2-yl)acetamide (C15H18N4O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2-((1-(2-Hydroxyethyl)-2-oxo-1,2,5,6,7,8-hexahydroquinazolin-4-yl)thio)-N-(thiazol-2-yl)acetamide 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.
