Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.20 g/mol gives N-Ethyl-3-methyl-2-nitroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-Ethyl-3-methyl-2-nitroaniline (CAS 160984-53-2), a certified reference material (molecular formula C9H12N2O2, MW 180.20 g/mol) for analytical method development and quality control.
The molecular framework of N-Ethyl-3-methyl-2-nitroaniline (C9H12N2O2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
