Chemical Structure
Description
The occurrence of (4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 2-chloro-6-fluorobenzoate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 2-chloro-6-fluorobenzoate (CAS 298188-08-6), molecular formula C12H6Cl3FN2O3 and molecular weight 351.55 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 2-chloro-6-fluorobenzoate (C12H6Cl3FN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (4,5-Dichloro-6-oxopyridazin-1(6H)-yl)methyl 2-chloro-6-fluorobenzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
