Description
CATO manufactures 4-Chloro-N-(3,4-dichlorophenyl)benzamide 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.
4-Chloro-N-(3,4-dichlorophenyl)benzamide (CAS 56661-50-8) is a high-purity analytical reference standard with the molecular formula C13H8Cl3NO and a molecular weight of 300.57 g/mol.
4-Chloro-N-(3,4-dichlorophenyl)benzamide (C13H8Cl3NO) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
