2-Methoxyethyl 7-methyl-2-(1-methyl-2-oxoindolin-3-ylidene)-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (CAS 618077-98-8), molecular formula C24H21N3O5S2 and molecular weight 495.57 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Methoxyethyl 7-methyl-2-(1-methyl-2-oxoindolin-3-ylidene)-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (C24H21N3O5S2) is characterized by a flavonoid core, 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 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.
CATO manufactures 2-Methoxyethyl 7-methyl-2-(1-methyl-2-oxoindolin-3-ylidene)-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation.
