Chemical Structure
Description
The molecular framework of N'-(cyclopropanecarbonyl)thieno[2,3-b]quinoline-2-carbohydrazide (C16H13N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
N'-(cyclopropanecarbonyl)thieno[2,3-b]quinoline-2-carbohydrazide (CAS 866131-37-5) is a high-purity analytical reference standard with the molecular formula C16H13N3O2S and a molecular weight of 311.36 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.
