Chemical Structure
Description
Based on its molecular formula C17H11N3, 91888-70-9 2-(Quinolin-2-yl)quinoxaline DTXSID30533290 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.29 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.
91888-70-9 2-(Quinolin-2-yl)quinoxaline DTXSID30533290 (CAS 91888-70-9) is a high-purity analytical reference standard with the molecular formula C17H11N3 and a molecular weight of 257.29 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
