Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 270.26 g/mol gives N1,N1-Diethyl-N2-methyl-N2-phenylethane-1,2-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N1,N1-Diethyl-N2-methyl-N2-phenylethane-1,2-diamine (CAS 74474-29-6), molecular formula C16H11FO3 and molecular weight 270.26 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H11FO3, N1,N1-Diethyl-N2-methyl-N2-phenylethane-1,2-diamine contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.26 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.
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.
