4-[(3,5-Dibromo-4-methoxyphenyl)methyl]-6-methyl-2-(methylamino)imidazo[4,5-d]azepin-5(6H)-one 634151-15-8 Ceratamine A (CAS 634151-15-8), molecular formula C17H16Br2N4O2 and molecular weight 468.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 4-[(3,5-Dibromo-4-methoxyphenyl)methyl]-6-methyl-2-(methylamino)imidazo[4,5-d]azepin-5(6H)-one 634151-15-8 Ceratamine A is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.14 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.
