Chemical Structure
Description
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.
Ethyl (R)-2-(6-fluoro-6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-1-yl)-2-oxoacetate (CAS 2407965-44-8) is a high-purity analytical reference standard with the molecular formula C10H11FN2O3 and a molecular weight of 226.20 g/mol.
Based on its molecular formula C10H11FN2O3, Ethyl (R)-2-(6-fluoro-6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-1-yl)-2-oxoacetate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.20 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.
