Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(2-bromoethyl)-1-methyl-1H-pyrazole hydrobromide (CAS 1311317-78-8), molecular formula C6H9BrN2HBr and molecular weight 269.97 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2-bromoethyl)-1-methyl-1H-pyrazole hydrobromide (C6H9BrN2HBr) contains a nitrile group, bromine substitution. 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.
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.
