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.
3,4-Dichloro-1,6-dimethylpyridin-2(1H)-one (CAS 1706432-20-3), molecular formula C7H7Cl2NO and molecular weight 192.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Dichloro-1,6-dimethylpyridin-2(1H)-one (C7H7Cl2NO) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.
