Chemical Structure
Description
Based on its molecular formula C16H20BrNO4, 4-(3-Bromophenyl)-1-(tert-butoxycarbonyl)pyrrolidine-3-carboxylic acid contains a flavonoid core, 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 370.24 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.
4-(3-Bromophenyl)-1-(tert-butoxycarbonyl)pyrrolidine-3-carboxylic acid (CAS 1823669-81-3) is a high-purity analytical reference standard with the molecular formula C16H20BrNO4 and a molecular weight of 370.24 g/mol.
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.
