Chemical Structure
Description
3-(6-Chloropyrazin-2-yl)imidazo[1,2-a]pyridine (CAS 1206970-18-4) is a high-purity analytical reference standard with the molecular formula C11H7ClN4 and a molecular weight of 230.65 g/mol.
Based on its molecular formula C11H7ClN4, 3-(6-Chloropyrazin-2-yl)imidazo[1,2-a]pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 230.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
