Chemical Structure
Description
4-bromo-3-fluoro-1H-pyrazolo[3,4-b]pyridine (CAS 2765270-33-3), molecular formula C6H11BrFN3 and molecular weight 224.07 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H11BrFN3, 4-bromo-3-fluoro-1H-pyrazolo[3,4-b]pyridine contains a nitrile group, fluorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 224.07 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.
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.
