Chemical Structure
Description
CATO supplies 6-Bromo-2-methyl-5-nitro-2,3-dihydroimidazo[2,1-b]oxazole (CAS 2095190-33-1), a certified reference material (molecular formula C6H6BrN3O3, MW 248.03 g/mol) for analytical method development and quality control.
6-Bromo-2-methyl-5-nitro-2,3-dihydroimidazo[2,1-b]oxazole (C6H6BrN3O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
