Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4-dichloropyrrolo[2,1-f][1,2,4]triazine-7-carboxylic acid (CAS 1784036-68-5) is a high-purity analytical reference standard with the molecular formula C7H11Cl2N3O2 and a molecular weight of 240.09 g/mol.
2,4-dichloropyrrolo[2,1-f][1,2,4]triazine-7-carboxylic acid (C7H11Cl2N3O2) contains an amide group, a carboxylic acid 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 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 2,4-dichloropyrrolo[2,1-f][1,2,4]triazine-7-carboxylic acid 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.
