Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 243.06 g/mol gives 3-Chloro-6-(4-chloro-2-fluorophenyl)pyridazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Chloro-6-(4-chloro-2-fluorophenyl)pyridazine (CAS 99708-45-9), a certified reference material (molecular formula C10H5Cl2FN2, MW 243.06 g/mol) for analytical method development and quality control.
3-Chloro-6-(4-chloro-2-fluorophenyl)pyridazine (C10H5Cl2FN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 manufactures 3-Chloro-6-(4-chloro-2-fluorophenyl)pyridazine 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.
