Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-1-methyl-1H-pyrazolo[3,4-b]pyridine.
3-Chloro-1-methyl-1H-pyrazolo[3,4-b]pyridine (CAS 116855-06-2), molecular formula C7H6ClN3 and molecular weight 167.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-1-methyl-1H-pyrazolo[3,4-b]pyridine (C7H6ClN3) is characterized by a nitrile group, chlorine 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 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 3-Chloro-1-methyl-1H-pyrazolo[3,4-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.
