Chemical Structure
Description
7-(Cyclopropylamino)thieno[3,2-b]pyridine-3,6-dicarboxylic acid hydrochloride (C12H10N2O4SHCl) contains a nitrogen-containing heterocyclic scaffold, 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.
7-(Cyclopropylamino)thieno[3,2-b]pyridine-3,6-dicarboxylic acid hydrochloride (CAS 2177258-28-3), molecular formula C12H10N2O4SHCl and molecular weight 314.74 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
