Diethyl 4H-thieno[3,2-b]pyrrole-2,5-dicarboxylate (CAS 89168-61-6), molecular formula C12H13NO4S and molecular weight 267.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Diethyl 4H-thieno[3,2-b]pyrrole-2,5-dicarboxylate (C12H13NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 267.30 g/mol, it falls into the medium-molecular-weight range. 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.
