Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Methanesulfonyl-2-[(4-methoxyphenyl)methanesulfinyl]-4,6-dimethylpyridine (CAS 339016-85-2), molecular formula C16H19NO4S2 and molecular weight 353.46 g/mol, is a CATO reference standard with documented purity and traceability.
3-Methanesulfonyl-2-[(4-methoxyphenyl)methanesulfinyl]-4,6-dimethylpyridine (C16H19NO4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
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.
