Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-5-{[tert-butyl(dimethyl)silyl]oxy}pyridine (CAS 1198765-41-1) is a high-purity analytical reference standard with the molecular formula C11H18BrNOSi and a molecular weight of 288.26 g/mol.
Based on its molecular formula C11H18BrNOSi, 2-Bromo-5-{[tert-butyl(dimethyl)silyl]oxy}pyridine contains an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
