Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 7-Bromo-4-chloropyrrolo[2,1-f][1,2,4]triazine-5-carboxylic acid (CAS 938191-85-6), a certified reference material (molecular formula C7H3BrClN3O2, MW 276.47 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H3BrClN3O2, 7-Bromo-4-chloropyrrolo[2,1-f][1,2,4]triazine-5-carboxylic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 276.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
