Chemical Structure
Description
Methyl 3-(((3-hydroxy-1-oxo-1H-inden-2-yl)methylene)amino)-4-methylthiophene-2-carboxylate (CAS 1022744-71-3) is a high-purity analytical reference standard with the molecular formula C17H13NO4S and a molecular weight of 327.35 g/mol.
The molecular framework of Methyl 3-(((3-hydroxy-1-oxo-1H-inden-2-yl)methylene)amino)-4-methylthiophene-2-carboxylate (C17H13NO4S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
