Chemical Structure
Description
6-Isopropyl-2-(4-(N-methyl-N-phenylsulfamoyl)benzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide (CAS 449768-53-0) is a high-purity analytical reference standard with the molecular formula C25H28N4O4S2HCl and a molecular weight of 549.10 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Isopropyl-2-(4-(N-methyl-N-phenylsulfamoyl)benzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 549.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
