Chemical Structure
Description
1-{pyrrolo[1,2-a]quinoxalin-4-yl}-1H-imidazole (CAS 478043-24-2), molecular formula C14H10N4 and molecular weight 234.26 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H10N4, 1-{pyrrolo[1,2-a]quinoxalin-4-yl}-1H-imidazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
