Chemical Structure
Description
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.
5631-68-5 A830997 N-methyl-3-nitro-4-pyridinamine N-methyl-3-nitro-pyridin-4-amine (CAS 5631-68-5) is a high-purity analytical reference standard with the molecular formula C9H16O4 and a molecular weight of 188.22 g/mol.
The molecular framework of 5631-68-5 A830997 N-methyl-3-nitro-4-pyridinamine N-methyl-3-nitro-pyridin-4-amine (C9H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
