3-bromo-4-chloro-1H-pyrazolo[3,4-b]pyridine (CAS 1357945-38-0), molecular formula C6H11BrClN3 and molecular weight 240.53 g/mol, is a CATO reference standard with documented purity and traceability.
3-bromo-4-chloro-1H-pyrazolo[3,4-b]pyridine (C6H11BrClN3) contains a nitrile group, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
