Chemical Structure
Description
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.
2,3-dibromo-5H,6H,7H,8H-imidazo[1,2-a]pyridin-6-amine (CAS 1803587-77-0) is a high-purity analytical reference standard with the molecular formula C7H9Br2N3 and a molecular weight of 294.97 g/mol.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 2,3-dibromo-5H,6H,7H,8H-imidazo[1,2-a]pyridin-6-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
