Chemical Structure
Description
As a certified reference material (CRM), 4-(6-Chloropyridazin-3-yl)piperazin-2-one 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.
4-(6-Chloropyridazin-3-yl)piperazin-2-one (CAS 1094291-62-9) is a high-purity analytical reference standard with the molecular formula C8H9ClN4O and a molecular weight of 212.64 g/mol.
The molecular framework of 4-(6-Chloropyridazin-3-yl)piperazin-2-one (C8H9ClN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
