1-Benzenesulfonyl-3-iodo-1H-pyrrolo[2,3-b]pyridine (CAS 887115-53-9), molecular formula C13H9IN2O2S and molecular weight 384.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Benzenesulfonyl-3-iodo-1H-pyrrolo[2,3-b]pyridine (C13H9IN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 384.19 g/mol, it falls into the moderately-high-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.
