Description
(E)-1-((4-bromo-3-methylphenyl)amino)-4-((2-fluoro-[1,1'-biphenyl]-4-yl)oxy)pent-1-en-3-one (CAS 477888-51-0), molecular formula C24H21BrFNO2 and molecular weight 454.33 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-1-((4-bromo-3-methylphenyl)amino)-4-((2-fluoro-[1,1'-biphenyl]-4-yl)oxy)pent-1-en-3-one (C24H21BrFNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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 454.33 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.
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.
