Chemical Structure

2-Methoxy-5-nitroaniline Monohydrochloride CAS 67827-72-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 204.61 g/mol gives 2-Methoxy-5-nitroaniline Monohydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methoxy-5-nitroaniline Monohydrochloride (CAS 67827-72-9) is a high-purity analytical reference standard with the molecular formula C7H8N2O3HCl and a molecular weight of 204.61 g/mol.

2-Methoxy-5-nitroaniline Monohydrochloride (C7H8N2O3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
