Description
CATO manufactures 2-Bromo-4-hydrazinylpyridine 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.
2-Bromo-4-hydrazinylpyridine (CAS 923547-35-7) is a high-purity analytical reference standard with the molecular formula C5H6BrN3 and a molecular weight of 188.03 g/mol.
The molecular framework of 2-Bromo-4-hydrazinylpyridine (C5H6BrN3) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
