Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl (R)-3-(4-bromophenyl)-2-((tert-butoxycarbonyl)amino)propanoate (CAS 1047975-40-5), a certified reference material (molecular formula C16H22BrNO4, MW 372.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H22BrNO4, Ethyl (R)-3-(4-bromophenyl)-2-((tert-butoxycarbonyl)amino)propanoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 372.25 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.
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.
