Chemical Structure
Description
The molecular framework of 4-bromo-3-chloro-1H-pyrazolo[3,4-b]pyridine (C6H11BrClN3) is characterized by a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-bromo-3-chloro-1H-pyrazolo[3,4-b]pyridine (CAS 1956385-09-3), molecular formula C6H11BrClN3 and molecular weight 240.53 g/mol, is a CATO reference standard with documented purity and traceability.
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.
