Chemical Structure

6-Methyl-6H-indolo[2,3-b]quinoxaline CAS 65880-39-9 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

6-Methyl-6H-indolo[2,3-b]quinoxaline (CAS 65880-39-9) is a high-purity analytical reference standard with the molecular formula C15H11N3 and a molecular weight of 233.27 g/mol.

6-Methyl-6H-indolo[2,3-b]quinoxaline (C15H11N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 6-Methyl-6H-indolo[2,3-b]quinoxaline 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.
