Chemical Structure

2-(4-Chlorophenyl)pyridine CAS 5969-83-5 chemical structure

Description

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.

2-(4-Chlorophenyl)pyridine (CAS 5969-83-5) is a high-purity analytical reference standard with the molecular formula C11H8ClN and a molecular weight of 189.64 g/mol.

The molecular framework of 2-(4-Chlorophenyl)pyridine (C11H8ClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
