Chemical Structure

6-Ethyl-9-methoxy-6H-indolo[2,3-b]quinoxaline CAS 697237-35-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 277.32 g/mol gives 6-Ethyl-9-methoxy-6H-indolo[2,3-b]quinoxaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-Ethyl-9-methoxy-6H-indolo[2,3-b]quinoxaline (CAS 697237-35-7), a certified reference material (molecular formula C17H15N3O, MW 277.32 g/mol) for analytical method development and quality control.

The molecular framework of 6-Ethyl-9-methoxy-6H-indolo[2,3-b]quinoxaline (C17H15N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

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), 6-Ethyl-9-methoxy-6H-indolo[2,3-b]quinoxaline 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.
