CATO supplies Methyl 2-(1-(4-bromophenyl)ethylidene)-1-(((2-((E)-1-(4-bromophenyl)ethylidene)hydrazine-1-carbonyl)oxy)methyl)hydrazine-1-carboxylate (CAS 1211461-40-3), a certified reference material (molecular formula C20H20Br2N4O4, MW 540.21 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H20Br2N4O4, Methyl 2-(1-(4-bromophenyl)ethylidene)-1-(((2-((E)-1-(4-bromophenyl)ethylidene)hydrazine-1-carbonyl)oxy)methyl)hydrazine-1-carboxylate contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 540.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Methyl 2-(1-(4-bromophenyl)ethylidene)-1-(((2-((E)-1-(4-bromophenyl)ethylidene)hydrazine-1-carbonyl)oxy)methyl)hydrazine-1-carboxylate 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.
