Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 4-(2-((4-(2-chlorophenyl)-3-cyano-6-phenylpyridin-2-yl)thio)acetamido)benzoate (CAS 332162-82-0) is a high-purity analytical reference standard with the molecular formula C28H20ClN3O3S and a molecular weight of 513.99 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl 4-(2-((4-(2-chlorophenyl)-3-cyano-6-phenylpyridin-2-yl)thio)acetamido)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 513.99 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).
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.
