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-Chloro-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one (CAS 76434-96-3), a certified reference material (molecular formula C4H2ClN5O, MW 171.54 g/mol) for analytical method development and quality control.
3-Chloro-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one (C4H2ClN5O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 3-Chloro-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one 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.
