Description
As a certified reference material (CRM), 2-(5-Bromo-2,3-dihydrobenzofuran-7-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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-(5-Bromo-2,3-dihydrobenzofuran-7-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2096333-86-5) is a high-purity analytical reference standard with the molecular formula C14H18BBrO3 and a molecular weight of 325.01 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-(5-Bromo-2,3-dihydrobenzofuran-7-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.01 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.
