Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 275.05 g/mol gives 2-Bromo-5-((trifluoromethyl)sulfinyl)pyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-5-((trifluoromethyl)sulfinyl)pyrazine (CAS 1206523-77-4) is a high-purity analytical reference standard with the molecular formula C5H2BrF3N2OS and a molecular weight of 275.05 g/mol.
The molecular framework of 2-Bromo-5-((trifluoromethyl)sulfinyl)pyrazine (C5H2BrF3N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
