Description
CATO manufactures 5-Bromo-1<I>H</I>-pyrazolo[4,3-<I>b</I>]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 5-Bromo-1<I>H</I>-pyrazolo[4,3-<I>b</I>]pyridine (CAS 1227628-78-5), a certified reference material (molecular formula C6H12BrN3, MW 206.08 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-1<I>H</I>-pyrazolo[4,3-<I>b</I>]pyridine (C6H12BrN3) is characterized by a nitrile group, 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.
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.
