Chemical Structure

2-Methoxy-2-(5-methoxy-2-nitrophenoxy)-acetic Acid Methyl Ester CAS 55544-88-2 chemical structure

Description

The molecular framework of 2-Methoxy-2-(5-methoxy-2-nitrophenoxy)-acetic Acid Methyl Ester (C11H13NO7) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

2-Methoxy-2-(5-methoxy-2-nitrophenoxy)-acetic Acid Methyl Ester (CAS 55544-88-2) is a high-purity analytical reference standard with the molecular formula C11H13NO7 and a molecular weight of 271.22 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.
