Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-amino-4,6-dimethyl-thieno[2,3-b]pyridine-2-carboxylic acid (CAS 58327-76-7) is a high-purity analytical reference standard with the molecular formula C10H18N2O2S and a molecular weight of 230.33 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-amino-4,6-dimethyl-thieno[2,3-b]pyridine-2-carboxylic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
