Ethyl 2-benzylidene-7-methyl-3-oxo-5-(p-tolyl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate CAS 324071-90-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 418.51 g/mol gives Ethyl 2-benzylidene-7-methyl-3-oxo-5-(p-tolyl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 2-benzylidene-7-methyl-3-oxo-5-(p-tolyl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (CAS 324071-90-1), a certified reference material (molecular formula C24H22N2O3S, MW 418.51 g/mol) for analytical method development and quality control.

Ethyl 2-benzylidene-7-methyl-3-oxo-5-(p-tolyl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (C24H22N2O3S) contains a steroid core, 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
