Chemical Structure
Description
As a certified reference material (CRM), N1,N1-di(naphthalen-2-yl)benzene-1,4-diamine 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.
N1,N1-di(naphthalen-2-yl)benzene-1,4-diamine (CAS 68941-03-7) is a high-purity analytical reference standard with the molecular formula C26H20N2 and a molecular weight of 360.45 g/mol.
Based on its molecular formula C26H20N2, N1,N1-di(naphthalen-2-yl)benzene-1,4-diamine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 360.45 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.
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.
