Description
Compared with other compounds in its class, the molecular weight of 238.33 g/mol gives 3-(o-Tolyl)-6,7,8,9-tetrahydro-5H-cyclohepta[c]pyridazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(o-Tolyl)-6,7,8,9-tetrahydro-5H-cyclohepta[c]pyridazine (CAS 918874-36-9), a certified reference material (molecular formula C16H18N2, MW 238.33 g/mol) for analytical method development and quality control.
The molecular framework of 3-(o-Tolyl)-6,7,8,9-tetrahydro-5H-cyclohepta[c]pyridazine (C16H18N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
