Description
CATO manufactures 3,5-Dichloropyridine-2,6-diamine 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.
CATO supplies 3,5-Dichloropyridine-2,6-diamine (CAS 76942-19-3), a certified reference material (molecular formula C5H5Cl2N3, MW 178.02 g/mol) for analytical method development and quality control.
3,5-Dichloropyridine-2,6-diamine (C5H5Cl2N3) contains a nitrile group, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
