Chemical Structure
Description
6-(tert-Butyl) 3-ethyl 2-iodo-4,7-dihydrothieno[2,3-c]pyridine-3,6(5H)-dicarboxylate (CAS 1384579-30-9), molecular formula C15H20INO4S and molecular weight 437.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution, 6-(tert-Butyl) 3-ethyl 2-iodo-4,7-dihydrothieno[2,3-c]pyridine-3,6(5H)-dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
