Chemical Structure

2-Chloro-5-methyl-3,3'-bipyridine CAS 1214366-91-2 chemical structure

Description

CATO supplies 2-Chloro-5-methyl-3,3'-bipyridine (CAS 1214366-91-2), a certified reference material (molecular formula C11H9ClN2, MW 204.66 g/mol) for analytical method development and quality control.

2-Chloro-5-methyl-3,3'-bipyridine (C11H9ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
