Chemical Structure
Description
2-((6-(4-Chlorophenyl)-3-cyano-4-phenylpyridin-2-yl)thio)-N-(3-nitrophenyl)acetamide (CAS 336174-00-6), molecular formula C26H17ClN4O3S and molecular weight 500.96 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-((6-(4-Chlorophenyl)-3-cyano-4-phenylpyridin-2-yl)thio)-N-(3-nitrophenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
