Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Imidazo[1,2-a]pyrido[2,3-e]pyrazin-4(5H)-one (CAS 133307-30-9), molecular formula C9H6N4O and molecular weight 186.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Imidazo[1,2-a]pyrido[2,3-e]pyrazin-4(5H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
