Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Nitro-1-(5-nitrothiophene-2-carbonyl)-2,3-dihydro-1H-indole (CAS 1798032-71-9), molecular formula C13H9N3O5S and molecular weight 319.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Nitro-1-(5-nitrothiophene-2-carbonyl)-2,3-dihydro-1H-indole (C13H9N3O5S) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
CATO manufactures 6-Nitro-1-(5-nitrothiophene-2-carbonyl)-2,3-dihydro-1H-indole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
