Chemical Structure
Description
3-((2-Chloro-5-nitrophenyl)amino)-1-(2,4,6-trichlorophenyl)-1H-pyrazol-5(4H)-one (CAS 30707-68-7), molecular formula C15H8Cl4N4O3 and molecular weight 434.06 g/mol, is a CATO reference standard with documented purity and traceability.
3-((2-Chloro-5-nitrophenyl)amino)-1-(2,4,6-trichlorophenyl)-1H-pyrazol-5(4H)-one (C15H8Cl4N4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.
As a certified reference material (CRM), 3-((2-Chloro-5-nitrophenyl)amino)-1-(2,4,6-trichlorophenyl)-1H-pyrazol-5(4H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
