Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 158.20 g/mol gives 2-Ethylquinoxaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Ethylquinoxaline (CAS 29750-44-5) is a high-purity analytical reference standard with the molecular formula C10H10N2 and a molecular weight of 158.20 g/mol.
Based on its molecular formula C10H10N2, 2-Ethylquinoxaline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 158.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Ethylquinoxaline 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.
