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 5-iodo-2,3-dihydrobenzo[b]furan.
5-iodo-2,3-dihydrobenzo[b]furan (CAS 132464-84-7), molecular formula C8H7IO and molecular weight 246.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-iodo-2,3-dihydrobenzo[b]furan (C8H7IO) is characterized by a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 5-iodo-2,3-dihydrobenzo[b]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.
