Chemical Structure
Description
CATO supplies 3-Benzyl-5-[(1E)-{[(3-chlorophenyl)methoxy]imino}methyl]-4-hydroxy-1-[2-(1H-imidazol-4-yl)ethyl]-1,2-dihydropyridin-2-one (CAS 477888-15-6), a certified reference material (molecular formula C25H23ClN4O3, MW 462.93 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Benzyl-5-[(1E)-{[(3-chlorophenyl)methoxy]imino}methyl]-4-hydroxy-1-[2-(1H-imidazol-4-yl)ethyl]-1,2-dihydropyridin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
