Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloropyridine-2,6-dicarbonyl dichloride.
4-Chloropyridine-2,6-dicarbonyl dichloride (CAS 71022-75-8), molecular formula C7H2Cl3NO2 and molecular weight 238.46 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloropyridine-2,6-dicarbonyl dichloride (C7H2Cl3NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
CATO manufactures 4-Chloropyridine-2,6-dicarbonyl dichloride 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.
