2,2'-((3-Chloro-5-nitropyrazine-2,6-diyl)bis(azanediyl))diethanol CAS 87591-68-2

Description

The molecular framework of 2,2'-((3-Chloro-5-nitropyrazine-2,6-diyl)bis(azanediyl))diethanol (C8H12ClN5O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).

2,2'-((3-Chloro-5-nitropyrazine-2,6-diyl)bis(azanediyl))diethanol (CAS 87591-68-2) is a high-purity analytical reference standard with the molecular formula C8H12ClN5O4 and a molecular weight of 277.66 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.
