Chemical Structure
Description
3-Bromo-1-ethyl-5-(pyrimidin-4-yl)pyridin-2(1H)-one (CAS 89996-06-5) is a high-purity analytical reference standard with the molecular formula C11H10BrN3O and a molecular weight of 280.12 g/mol.
Structurally, 3-Bromo-1-ethyl-5-(pyrimidin-4-yl)pyridin-2(1H)-one (C11H10BrN3O) 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 280.12 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
