Chemical Structure
Description
1,8-Dimethylimidazo[1,2-a]quinoxalin-4(5H)-one (CAS 445430-61-5), molecular formula C12H11N3O and molecular weight 213.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,8-Dimethylimidazo[1,2-a]quinoxalin-4(5H)-one (C12H11N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 213.24 g/mol, it falls into the medium-molecular-weight range. 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.
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.
