Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 364.80 g/mol gives 3-Cyano-4,6-dimethylpyridin-2-yl 2-chloro-4-(methylsulfonyl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Cyano-4,6-dimethylpyridin-2-yl 2-chloro-4-(methylsulfonyl)benzoate (CAS 338421-40-2), molecular formula C16H13ClN2O4S and molecular weight 364.80 g/mol, is a CATO reference standard with documented purity and traceability.
3-Cyano-4,6-dimethylpyridin-2-yl 2-chloro-4-(methylsulfonyl)benzoate (C16H13ClN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
