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-Chloro-1-(3,5-dimethyl-4-nitro-1H-pyrazol-1-yl)ethanone (CAS 514217-68-6) is a high-purity analytical reference standard with the molecular formula C7H8ClN3O3 and a molecular weight of 217.61 g/mol.
2-Chloro-1-(3,5-dimethyl-4-nitro-1H-pyrazol-1-yl)ethanone (C7H8ClN3O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-Chloro-1-(3,5-dimethyl-4-nitro-1H-pyrazol-1-yl)ethanone 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.
