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.
5-Bromo-1-methyl-3-((5-(3-methyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-yl)amino)pyridin-2(1H)-one (CAS 1624262-37-8) is a high-purity analytical reference standard with the molecular formula C19H24BrN5O2 and a molecular weight of 434.33 g/mol.
Structurally, 5-Bromo-1-methyl-3-((5-(3-methyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-yl)amino)pyridin-2(1H)-one (C19H24BrN5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 434.33 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
