Chemical Structure
Description
CATO supplies 4-Chloro-6-(pyridin-3-yl)pyrimidine (CAS 954232-31-6), a certified reference material (molecular formula C9H6ClN3, MW 191.62 g/mol) for analytical method development and quality control.
4-Chloro-6-(pyridin-3-yl)pyrimidine (C9H6ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
