Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dimethoxyquinoxaline.
6,7-Dimethoxyquinoxaline (CAS 6295-29-0) is a high-purity analytical reference standard with the molecular formula C10H10N2O2 and a molecular weight of 190.20 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 6,7-Dimethoxyquinoxaline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.20 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.
As a certified reference material (CRM), 6,7-Dimethoxyquinoxaline 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.
