Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Dibenzo[b,d]selenophene 5-oxide (CAS 30467-70-0), molecular formula C12H8OSe and molecular weight 247.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, Dibenzo[b,d]selenophene 5-oxide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 247.15 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).
As a certified reference material (CRM), Dibenzo[b,d]selenophene 5-oxide 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.
