Chemical Structure
Description
The molecular framework of Methyl 5,6-dimethoxy-1H-indole-1-carboxylate (C12H13NO4) is characterized by an amino-acid-derived structure, an amide 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).
Methyl 5,6-dimethoxy-1H-indole-1-carboxylate (CAS 77468-98-5) is a high-purity analytical reference standard with the molecular formula C12H13NO4 and a molecular weight of 235.24 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl 5,6-dimethoxy-1H-indole-1-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.
