Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,8-Dibromo-5-methylimidazo[1,2-a]pyrazine.
6,8-Dibromo-5-methylimidazo[1,2-a]pyrazine (CAS 909907-19-3) is a high-purity analytical reference standard with the molecular formula C7H5Br2N3 and a molecular weight of 290.94 g/mol.
6,8-Dibromo-5-methylimidazo[1,2-a]pyrazine (C7H5Br2N3) contains a nitrile group, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
