Description
As a certified reference material (CRM), 8-Methylpyrrolo[1,2-a]quinoxalin-4(5H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
8-Methylpyrrolo[1,2-a]quinoxalin-4(5H)-one (CAS 159548-94-4) is a high-purity analytical reference standard with the molecular formula C12H10N2O and a molecular weight of 198.22 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 8-Methylpyrrolo[1,2-a]quinoxalin-4(5H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 198.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
