Description
CATO manufactures 2-Chloro-3,5-dinitrobenzamide 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.
2-Chloro-3,5-dinitrobenzamide (CAS 6266-51-9) is a high-purity analytical reference standard with the molecular formula C7H4ClN3O5 and a molecular weight of 245.58 g/mol.
The molecular framework of 2-Chloro-3,5-dinitrobenzamide (C7H4ClN3O5) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
