Chemical Structure
Description
The occurrence of Potassium 5-bromo-1H-imidazole-2-carboxylate is closely related to a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Potassium 5-bromo-1H-imidazole-2-carboxylate (CAS 2089335-03-3), a certified reference material (molecular formula C4H2BrN2O2K, MW 229.07 g/mol) for analytical method development and quality control.
Potassium 5-bromo-1H-imidazole-2-carboxylate (C4H2BrN2O2K) contains a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
