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.
4-Oxo-4-{4h,5h,6h,7h-thieno[3,2-c]pyridin-5-yl}butanoic acid (CAS 926252-17-7), molecular formula C11H13NO3S and molecular weight 239.29 g/mol, is a CATO reference standard with documented purity and traceability.
4-Oxo-4-{4h,5h,6h,7h-thieno[3,2-c]pyridin-5-yl}butanoic acid (C11H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
