Chemical Structure
Description
Dimethyl 5-(m-tolyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2-oxide (C17H17NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
Dimethyl 5-(m-tolyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2-oxide (CAS 339113-52-9) is a high-purity analytical reference standard with the molecular formula C17H17NO5S and a molecular weight of 347.39 g/mol.
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.
