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)-N-Cyclohexyl-N'-[(2,4-dichlorophenyl)methyl]-N''-phenylguanidine (CAS 338414-79-2), a certified reference material (molecular formula C20H23Cl2N3, MW 376.32 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H23Cl2N3, (E)-N-Cyclohexyl-N'-[(2,4-dichlorophenyl)methyl]-N''-phenylguanidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 376.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
