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.
6-Chloropyridine-2,3-dicarbonitrile (CAS 401565-17-1), molecular formula C7H2ClN3 and molecular weight 163.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Chloropyridine-2,3-dicarbonitrile (C7H2ClN3) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
