Chemical Structure

4-Ethoxydibenzo[b,d]furan CAS 685873-95-4 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 4-Ethoxydibenzo[b,d]furan.

4-Ethoxydibenzo[b,d]furan (CAS 685873-95-4) is a high-purity analytical reference standard with the molecular formula C14H12O2 and a molecular weight of 212.24 g/mol.

The molecular framework of 4-Ethoxydibenzo[b,d]furan (C14H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-Ethoxydibenzo[b,d]furan 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.
