Description
CATO manufactures 7-Chloro-3-iodo-1H-pyrazolo[4,3-b]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 7-Chloro-3-iodo-1H-pyrazolo[4,3-b]pyridine (CAS 1357945-92-6), a certified reference material (molecular formula C6H3ClIN3, MW 279.47 g/mol) for analytical method development and quality control.
The molecular framework of 7-Chloro-3-iodo-1H-pyrazolo[4,3-b]pyridine (C6H3ClIN3) is characterized by a nitrile group, chlorine/iodine substitution, an aromatic ring system. 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.
