Chemical Structure
Description
As a certified reference material (CRM), 1,3-Dihydrofuro[3,4-b]quinoxalin-1-ol 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.
1,3-Dihydrofuro[3,4-b]quinoxalin-1-ol (CAS 23012-72-8) is a high-purity analytical reference standard with the molecular formula C10H8N2O2 and a molecular weight of 188.18 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1,3-Dihydrofuro[3,4-b]quinoxalin-1-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.18 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.
