Description
As a certified reference material (CRM), 3-Amino-4,5-dicyano-1H-pyrazole-1-carbonyl chloride 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.
CATO supplies 3-Amino-4,5-dicyano-1H-pyrazole-1-carbonyl chloride (CAS 89875-96-7), a certified reference material (molecular formula C6H2ClN5O, MW 195.57 g/mol) for analytical method development and quality control.
3-Amino-4,5-dicyano-1H-pyrazole-1-carbonyl chloride (C6H2ClN5O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
