Chemical Structure
Description
CATO supplies 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-b]pyridine (CAS 933705-52-3), a certified reference material (molecular formula C6H9N3, MW 123.16 g/mol) for analytical method development and quality control.
The molecular framework of 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-b]pyridine (C6H9N3) is characterized by a nitrile group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,5,6,7-Tetrahydro-2H-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.
