Description
As a certified reference material (CRM), 1-(5-Bromobenzofuran-2-yl)ethane-1-thiol 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.
1-(5-Bromobenzofuran-2-yl)ethane-1-thiol (CAS 1038981-94-0) is a high-purity analytical reference standard with the molecular formula C10H9BrOS and a molecular weight of 257.15 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-(5-Bromobenzofuran-2-yl)ethane-1-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.15 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.
