Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Bromo-6,7-dihydrobenzo[b]thiophen-4(5h)-one (CAS 2513-49-7), a certified reference material (molecular formula C8H7BrOS, MW 231.11 g/mol) for analytical method development and quality control.
Structurally, 5-Bromo-6,7-dihydrobenzo[b]thiophen-4(5h)-one (C8H7BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 231.11 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
