Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-bromo-1-(4-chloro-1-methyl-pyrazol-3-yl)ethanone (CAS 2068151-92-6) is a high-purity analytical reference standard with the molecular formula C6H10BrClN2O and a molecular weight of 241.51 g/mol.
2-bromo-1-(4-chloro-1-methyl-pyrazol-3-yl)ethanone (C6H10BrClN2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
