Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4,6-dichloro-2-methyl-2H-pyrazolo[3,4-d]pyrimidine (CAS 959432-77-0), a certified reference material (molecular formula C6H12Cl2N4, MW 211.09 g/mol) for analytical method development and quality control.
The molecular framework of 4,6-dichloro-2-methyl-2H-pyrazolo[3,4-d]pyrimidine (C6H12Cl2N4) 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.
CATO manufactures 4,6-dichloro-2-methyl-2H-pyrazolo[3,4-d]pyrimidine 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.
