Methyl 7-amino-2-(4-methoxyphenyl)-3-oxo-2H,3H-thieno[3,2-c]pyridazine-6-carboxylate CAS 338395-94-1

Description

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.

Methyl 7-amino-2-(4-methoxyphenyl)-3-oxo-2H,3H-thieno[3,2-c]pyridazine-6-carboxylate (CAS 338395-94-1) is a high-purity analytical reference standard with the molecular formula C15H13N3O4S and a molecular weight of 331.35 g/mol.

The molecular framework of Methyl 7-amino-2-(4-methoxyphenyl)-3-oxo-2H,3H-thieno[3,2-c]pyridazine-6-carboxylate (C15H13N3O4S) 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.
