6-Ethyl-2-(4-methylbenzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride CAS 1215817-30-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 379.90 g/mol gives 6-Ethyl-2-(4-methylbenzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Ethyl-2-(4-methylbenzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (CAS 1215817-30-3) is a high-purity analytical reference standard with the molecular formula C18H21N3O2SHCl and a molecular weight of 379.90 g/mol.

6-Ethyl-2-(4-methylbenzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (C18H21N3O2SHCl) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
