Chemical Structure
Description
2-Bromo-6,6-dimethyl-5,6-dihydrobenzo[b]thiophen-7(4H)-one (CAS 1800550-07-5) is a high-purity analytical reference standard with the molecular formula C10H11BrOS and a molecular weight of 259.16 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-6,6-dimethyl-5,6-dihydrobenzo[b]thiophen-7(4H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-Bromo-6,6-dimethyl-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.
