4-Chloro-3-nitropyridine CAS 13091-23-1

Description

Compared with other compounds in its class, the molecular weight of 164.59 g/mol gives 4-Chloro-3-nitropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Chloro-3-nitropyridine (CAS 13091-23-1), a certified reference material (molecular formula C5H9ClN2O2, MW 164.59 g/mol) for analytical method development and quality control.

Structurally, 4-Chloro-3-nitropyridine (C5H9ClN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 164.59 g/mol, it falls into the medium-molecular-weight range. 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.
