3-Amino-6-ethyl-N-[(2-methoxyphenyl)methyl]-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide CAS 445268-91-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-6-ethyl-N-[(2-methoxyphenyl)methyl]-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide.

3-Amino-6-ethyl-N-[(2-methoxyphenyl)methyl]-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide (CAS 445268-91-7), molecular formula C22H25N3O2S and molecular weight 395.52 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C22H25N3O2S, 3-Amino-6-ethyl-N-[(2-methoxyphenyl)methyl]-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 395.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
