Chemical Structure
Description
4-Butoxy-2-(chloromethyl)-5-morpholinopyridazin-3(2H)-one (CAS 63431-52-7) is a high-purity analytical reference standard with the molecular formula C13H20ClN3O3 and a molecular weight of 301.77 g/mol.
The molecular framework of 4-Butoxy-2-(chloromethyl)-5-morpholinopyridazin-3(2H)-one (C13H20ClN3O3) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
