Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies 3-Chloro-6-(pyrrolidine-1-carbonyl)pyridazine (CAS 1182931-73-2), a certified reference material (molecular formula C9H10ClN3O, MW 211.65 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chloro-6-(pyrrolidine-1-carbonyl)pyridazine (C9H10ClN3O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 3-Chloro-6-(pyrrolidine-1-carbonyl)pyridazine 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.
