Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-chloro-7-methyl-[1,2,4]triazolo[4,3-c]pyrimidine (CAS 2137684-12-7) is a high-purity analytical reference standard with the molecular formula C6H5ClN4 and a molecular weight of 168.58 g/mol.
The molecular framework of 3-chloro-7-methyl-[1,2,4]triazolo[4,3-c]pyrimidine (C6H5ClN4) 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).
CATO manufactures 3-chloro-7-methyl-[1,2,4]triazolo[4,3-c]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.
