Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 231.20 g/mol gives 3-(2-NItrophenoxy)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(2-NItrophenoxy)phenol (CAS 74683-21-9) is a high-purity analytical reference standard with the molecular formula C12H9NO4 and a molecular weight of 231.20 g/mol.
The molecular framework of 3-(2-NItrophenoxy)phenol (C12H9NO4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
