Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 1-(benzenesulfonyl)-5-nitro-1H-pyrrolo[2,3-b]pyridine-3-carboxylate (CAS 858340-91-7) is a high-purity analytical reference standard with the molecular formula C15H11N3O6S and a molecular weight of 361.33 g/mol.
The molecular framework of Methyl 1-(benzenesulfonyl)-5-nitro-1H-pyrrolo[2,3-b]pyridine-3-carboxylate (C15H11N3O6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), Methyl 1-(benzenesulfonyl)-5-nitro-1H-pyrrolo[2,3-b]pyridine-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
