Isopropyl 2-(1-ethyl-2-oxoindolin-3-ylidene)-7-methyl-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (CAS 618078-14-1) is a high-purity analytical reference standard with the molecular formula C25H23N3O4S2 and a molecular weight of 493.60 g/mol.
The molecular framework of Isopropyl 2-(1-ethyl-2-oxoindolin-3-ylidene)-7-methyl-3-oxo-5-(thiophen-2-yl)-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate (C25H23N3O4S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
