Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5,7-Dibromo-2-(2-(5-nitrofuran-2-yl)vinyl)benzofuran (CAS 89266-58-0), molecular formula C14H7Br2NO4 and molecular weight 413.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5,7-Dibromo-2-(2-(5-nitrofuran-2-yl)vinyl)benzofuran (C14H7Br2NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 413.02 g/mol, it falls into the moderately-high-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.
