Description
CATO supplies 5-{5,6-dichloro-1-[(3,4-dichlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one (CAS 338773-96-9), a certified reference material (molecular formula C19H11Cl4N3O, MW 439.12 g/mol) for analytical method development and quality control.
Structurally, 5-{5,6-dichloro-1-[(3,4-dichlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one (C19H11Cl4N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 439.12 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
