Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 6-amino-5-cyano-2-[({5-cyano-[2,4'-bipyridine]-6-yl}sulfanyl)methyl]-4-(4-methoxyphenyl)-4H-pyran-3-carboxylate (CAS 313380-24-4), molecular formula C28H23N5O4S and molecular weight 525.58 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, Ethyl 6-amino-5-cyano-2-[({5-cyano-[2,4'-bipyridine]-6-yl}sulfanyl)methyl]-4-(4-methoxyphenyl)-4H-pyran-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 525.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
