2,3-Diphenylbutane-2,3-diamine CAS 109090-35-9

Description

Compared with other compounds in its class, the molecular weight of 240.34 g/mol gives 2,3-Diphenylbutane-2,3-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3-Diphenylbutane-2,3-diamine (CAS 109090-35-9) is a high-purity analytical reference standard with the molecular formula C16H20N2 and a molecular weight of 240.34 g/mol.

Based on its molecular formula C16H20N2, 2,3-Diphenylbutane-2,3-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 240.34 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.
