Chemical Structure

4-Nitroaniline CAS 100-01-6 chemical structure

Description

Based on its molecular formula C6H6N2O2, 4-Nitroaniline contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 138.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

4-Nitroaniline (CAS 100-01-6) is a high-purity analytical reference standard with the molecular formula C6H6N2O2 and a molecular weight of 138.12 g/mol.

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.
