Chemical Structure
Description
2',4'-Difluoro-[1,1'-biphenyl]-4-amine (CAS 62575-36-4) is a high-purity analytical reference standard with the molecular formula C12H9F2N and a molecular weight of 205.20 g/mol.
Based on its molecular formula C12H9F2N, 2',4'-Difluoro-[1,1'-biphenyl]-4-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
