Chemical Structure
Description
1-(5-Chloro-1-ethyl-6-oxo-1,6-dihydropyridazin-4-yl)pyrrolidine-3-carboxylic acid (CAS 1708288-16-7) is a high-purity analytical reference standard with the molecular formula C11H14ClN3O3 and a molecular weight of 271.70 g/mol.
1-(5-Chloro-1-ethyl-6-oxo-1,6-dihydropyridazin-4-yl)pyrrolidine-3-carboxylic acid (C11H14ClN3O3) 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.
As a certified reference material (CRM), 1-(5-Chloro-1-ethyl-6-oxo-1,6-dihydropyridazin-4-yl)pyrrolidine-3-carboxylic acid 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.
