Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 2-[1-(3-chlorophenyl)-3,5-dimethyl-1h-pyrazol-4-yl]-2-(n-hydroxyimino)acetate (CAS 1006482-03-6), molecular formula C15H16ClN3O3 and molecular weight 321.76 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-[1-(3-chlorophenyl)-3,5-dimethyl-1h-pyrazol-4-yl]-2-(n-hydroxyimino)acetate (C15H16ClN3O3) contains a nitrogen-containing heterocyclic scaffold, an amide 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Ethyl 2-[1-(3-chlorophenyl)-3,5-dimethyl-1h-pyrazol-4-yl]-2-(n-hydroxyimino)acetate 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.
