Chemical Structure

(E)-1-Methyl-3-styrylquinoxalin-2(1H)-one CAS 93585-00-3 chemical structure

Description

As a certified reference material (CRM), (E)-1-Methyl-3-styrylquinoxalin-2(1H)-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.

(E)-1-Methyl-3-styrylquinoxalin-2(1H)-one (CAS 93585-00-3) is a high-purity analytical reference standard with the molecular formula C17H14N2O and a molecular weight of 262.31 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (E)-1-Methyl-3-styrylquinoxalin-2(1H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 262.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
