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 Methyl6-chloro-1h-pyrazolo[4,3-c]pyridine-3-carboxylate.
CATO supplies Methyl6-chloro-1h-pyrazolo[4,3-c]pyridine-3-carboxylate (CAS 1658461-71-2), a certified reference material (molecular formula C8H6ClN3O2, MW 211.61 g/mol) for analytical method development and quality control.
The molecular framework of Methyl6-chloro-1h-pyrazolo[4,3-c]pyridine-3-carboxylate (C8H6ClN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
CATO manufactures Methyl6-chloro-1h-pyrazolo[4,3-c]pyridine-3-carboxylate 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.
