Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 1-(6-Bromopyridin-2-yl)piperazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(6-Bromopyridin-2-yl)piperazine (CAS 219635-91-3) is a high-purity analytical reference standard with the molecular formula C9H12BrN3 and a molecular weight of 242.12 g/mol.
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.
