Description
Compared with other compounds in its class, the molecular weight of 325.75 g/mol gives 7-Chloro-5-((3-methyl-1H-indol-7-yl)amino)pyrido[3,4-d]pyridazin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Chloro-5-((3-methyl-1H-indol-7-yl)amino)pyrido[3,4-d]pyridazin-4(3H)-one (CAS 1564273-29-5), molecular formula C16H12ClN5O and molecular weight 325.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Chloro-5-((3-methyl-1H-indol-7-yl)amino)pyrido[3,4-d]pyridazin-4(3H)-one (C16H12ClN5O) 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.
