Diethyl 9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylate CAS 83742-19-2

Description

As a certified reference material (CRM), Diethyl 9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylate 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.

Diethyl 9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylate (CAS 83742-19-2), molecular formula C22H22O4 and molecular weight 350.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Diethyl 9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.41 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.
