25966-39-6 A818112 N-[2-(2,4-dinitrophenyl)azo-5-[(2-hydroxy-3-methoxypropyl)amino]-4-methoxyphenyl]acetamide N-[2-[(2,4-dinitrophenyl)diazenyl]-4-methoxy-5-[(3-methoxy-2-oxidanyl-propyl)amino]phenyl]ethanamide (CAS 25966-39-6) is a high-purity analytical reference standard with the molecular formula C5H7BrO2 and a molecular weight of 179.01 g/mol.
25966-39-6 A818112 N-[2-(2,4-dinitrophenyl)azo-5-[(2-hydroxy-3-methoxypropyl)amino]-4-methoxyphenyl]acetamide N-[2-[(2,4-dinitrophenyl)diazenyl]-4-methoxy-5-[(3-methoxy-2-oxidanyl-propyl)amino]phenyl]ethanamide (C5H7BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
