Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including lithium(1+) ion 2-bromo-1-ethyl-1H-imidazole-5-carboxylate.
CATO supplies lithium(1+) ion 2-bromo-1-ethyl-1H-imidazole-5-carboxylate (CAS 1989671-44-4), a certified reference material (molecular formula C6H6BrN2O2Li, MW 224.97 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H6BrN2O2Li, lithium(1+) ion 2-bromo-1-ethyl-1H-imidazole-5-carboxylate contains a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 224.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
