Chemical Structure

[4,4'-Bipyridine]-2,2'-diamine CAS 189000-91-7 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, [4,4'-Bipyridine]-2,2'-diamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

[4,4'-Bipyridine]-2,2'-diamine (CAS 189000-91-7) is a high-purity analytical reference standard with the molecular formula C10H10N4 and a molecular weight of 186.21 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.
