Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-Chloro-3-(2-fluorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine (CAS 119222-29-6), molecular formula C11H7ClFN5 and molecular weight 263.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Chloro-3-(2-fluorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine (C11H7ClFN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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 7-Chloro-3-(2-fluorobenzyl)-3H-[1,2,3]triazolo[4,5-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.
