4,4′-Diethyl [1,1′-biphenyl]-4,4′-dicarboxylate CAS 47230-38-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4′-Diethyl [1,1′-biphenyl]-4,4′-dicarboxylate.

4,4′-Diethyl [1,1′-biphenyl]-4,4′-dicarboxylate (CAS 47230-38-6), molecular formula C18H18O4 and molecular weight 298.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 4,4′-Diethyl [1,1′-biphenyl]-4,4′-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.33 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.

As a certified reference material (CRM), 4,4′-Diethyl [1,1′-biphenyl]-4,4′-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.
