Description
CATO manufactures 1-(4-chloro-3-fluorophenyl)imidazolidine-2,4,5-trione 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.
1-(4-chloro-3-fluorophenyl)imidazolidine-2,4,5-trione (CAS 1249751-76-5) is a high-purity analytical reference standard with the molecular formula C9H4ClFN2O3 and a molecular weight of 242.59 g/mol.
1-(4-chloro-3-fluorophenyl)imidazolidine-2,4,5-trione (C9H4ClFN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
