Description

As a certified reference material (CRM), 2-Methoxyethyl 2-(2-chlorobenzylidene)-7-methyl-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate 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.

CATO supplies 2-Methoxyethyl 2-(2-chlorobenzylidene)-7-methyl-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (CAS 617698-62-1), a certified reference material (molecular formula C22H19ClN2O4S2, MW 474.98 g/mol) for analytical method development and quality control.

2-Methoxyethyl 2-(2-chlorobenzylidene)-7-methyl-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (C22H19ClN2O4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
