Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 6'-Chloro-2,3'-bipyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.63 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).
6'-Chloro-2,3'-bipyridine (CAS 93297-75-7) is a high-purity analytical reference standard with the molecular formula C10H7ClN2 and a molecular weight of 190.63 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.
