Chemical Structure
Description
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.
3-bromo-5-(2-methyl-1H-imidazol-1-yl)pyridine (CAS 1289078-48-3) is a high-purity analytical reference standard with the molecular formula C9H8BrN3 and a molecular weight of 238.08 g/mol.
3-bromo-5-(2-methyl-1H-imidazol-1-yl)pyridine (C9H8BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
