Chemical Structure
Description
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 supplies (E)-2-chloro-1-(5-((2-(2,4-dinitrophenyl)hydrazono)methyl)-1H-pyrrol-3-yl)ethan-1-one (CAS 866142-88-3), a certified reference material (molecular formula C13H10ClN5O5, MW 351.70 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 substitution, (E)-2-chloro-1-(5-((2-(2,4-dinitrophenyl)hydrazono)methyl)-1H-pyrrol-3-yl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 351.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (E)-2-chloro-1-(5-((2-(2,4-dinitrophenyl)hydrazono)methyl)-1H-pyrrol-3-yl)ethan-1-one 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.
