Chemical Structure
Description
(4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 3-(trifluoromethyl)benzoate (CAS 439107-90-1) is a high-purity analytical reference standard with the molecular formula C13H7Cl2F3N2O3 and a molecular weight of 367.11 g/mol.
(4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 3-(trifluoromethyl)benzoate (C13H7Cl2F3N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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. 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 (4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 3-(trifluoromethyl)benzoate 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.
