Description
Compared with other compounds in its class, the molecular weight of 270.74 g/mol gives Methyl 3-amino-5-chloro-4,6-dimethylthieno[2,3-b]pyridine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 3-amino-5-chloro-4,6-dimethylthieno[2,3-b]pyridine-2-carboxylate (CAS 841261-58-3) is a high-purity analytical reference standard with the molecular formula C11H11ClN2O2S and a molecular weight of 270.74 g/mol.
Methyl 3-amino-5-chloro-4,6-dimethylthieno[2,3-b]pyridine-2-carboxylate (C11H11ClN2O2S) 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, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
