Chemical Structure
Description
As a certified reference material (CRM), 1-(3-Chlorophenyl)pyrazolidine-3,5-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1-(3-Chlorophenyl)pyrazolidine-3,5-dione (CAS 355829-30-0) is a high-purity analytical reference standard with the molecular formula C9H7ClN2O2 and a molecular weight of 210.62 g/mol.
1-(3-Chlorophenyl)pyrazolidine-3,5-dione (C9H7ClN2O2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
