Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Chloro-N-(4-chlorobenzyl)pyrazine-2-carboxamide (CAS 1426690-31-4) is a high-purity analytical reference standard with the molecular formula C12H9Cl2N3O and a molecular weight of 282.13 g/mol.
5-Chloro-N-(4-chlorobenzyl)pyrazine-2-carboxamide (C12H9Cl2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 5-Chloro-N-(4-chlorobenzyl)pyrazine-2-carboxamide 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.
