Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dihydro-2H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3(5H)-one.
6,7-Dihydro-2H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3(5H)-one (CAS 25823-52-3), molecular formula C13H12N2O and molecular weight 212.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6,7-Dihydro-2H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3(5H)-one (C13H12N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
As a certified reference material (CRM), 6,7-Dihydro-2H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3(5H)-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.
