Description
As a certified reference material (CRM), (4,5-Dibromo-6-oxo-1,6-dihydropyridazin-1-yl)methyl 3,4-dichlorobenzoate 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.
CATO supplies (4,5-Dibromo-6-oxo-1,6-dihydropyridazin-1-yl)methyl 3,4-dichlorobenzoate (CAS 439108-06-2), a certified reference material (molecular formula C12H6Br2Cl2N2O3, MW 456.90 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, (4,5-Dibromo-6-oxo-1,6-dihydropyridazin-1-yl)methyl 3,4-dichlorobenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 456.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
