Chemical Structure
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.
CATO supplies Ethyl 4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate hydrochloride (CAS 2841454-00-8), a certified reference material (molecular formula C10H13NO2SHCl, MW 247.74 g/mol) for analytical method development and quality control.
Ethyl 4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate hydrochloride (C10H13NO2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
