Chemical Structure

Quinoxalino[2,3-b]quinoxaline CAS 258-14-0 chemical structure

Description

Quinoxalino[2,3-b]quinoxaline (CAS 258-14-0) is a high-purity analytical reference standard with the molecular formula C14H8N4 and a molecular weight of 232.24 g/mol.

Based on its molecular formula C14H8N4, Quinoxalino[2,3-b]quinoxaline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 232.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Quinoxalino[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.
