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 6-(2-Chlorophenoxy)-2-(2-hydroxyethyl)pyridazin-3(2H)-one (CAS 69024-93-7), a certified reference material (molecular formula C12H11ClN2O3, MW 266.68 g/mol) for analytical method development and quality control.
6-(2-Chlorophenoxy)-2-(2-hydroxyethyl)pyridazin-3(2H)-one (C12H11ClN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 6-(2-Chlorophenoxy)-2-(2-hydroxyethyl)pyridazin-3(2H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
