Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3,4,5,6-Tetrachloropicolinonitrile (CAS 17824-83-8), a certified reference material (molecular formula C6Cl4N2, MW 241.89 g/mol) for analytical method development and quality control.
3,4,5,6-Tetrachloropicolinonitrile (C6Cl4N2) contains a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 3,4,5,6-Tetrachloropicolinonitrile 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.
