Description
As a certified reference material (CRM), 2-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one 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.
2-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one (CAS 1369138-74-8) is a high-purity analytical reference standard with the molecular formula C8H7BrOS and a molecular weight of 231.11 g/mol.
The molecular framework of 2-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one (C8H7BrOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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.
