Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-5-Bromo-N,N-bis-(tert-butoxycarbonyl)-3-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)pyridin-2-amine.
(R)-5-Bromo-N,N-bis-(tert-butoxycarbonyl)-3-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)pyridin-2-amine (CAS 877399-47-8) is a high-purity analytical reference standard with the molecular formula C23H26BrCl2FN2O5 and a molecular weight of 580.27 g/mol.
Based on its molecular formula C23H26BrCl2FN2O5, (R)-5-Bromo-N,N-bis-(tert-butoxycarbonyl)-3-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)pyridin-2-amine contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 580.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
