Description
CATO manufactures 4-chloro-7-methyl-1H-pyrazolo[4,3-c]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 4-chloro-7-methyl-1H-pyrazolo[4,3-c]pyridine (CAS 1159828-57-5), a certified reference material (molecular formula C7H14ClN3, MW 175.66 g/mol) for analytical method development and quality control.
The molecular framework of 4-chloro-7-methyl-1H-pyrazolo[4,3-c]pyridine (C7H14ClN3) is characterized by a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
