Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-2-[2-(4-Chlorophenyl)hydrazin-1-ylidene]-3-(furan-2-yl)-3-oxopropanal.
(2E)-2-[2-(4-Chlorophenyl)hydrazin-1-ylidene]-3-(furan-2-yl)-3-oxopropanal (CAS 338400-29-6), molecular formula C13H9ClN2O3 and molecular weight 276.68 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H9ClN2O3, (2E)-2-[2-(4-Chlorophenyl)hydrazin-1-ylidene]-3-(furan-2-yl)-3-oxopropanal contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 276.68 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
