Chemical Structure
Description
The occurrence of 5-Bromoimidazo[1,2-a]pyrazine, 97% is closely related to a nitrile group, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromoimidazo[1,2-a]pyrazine, 97% (CAS 87597-26-0), molecular formula C6H4BrN3 and molecular weight 198.02 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 5-Bromoimidazo[1,2-a]pyrazine, 97% is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
