Chemical Structure

(S)-5'-Bromo-2',3'-dihydrospiro[imidazolidine-4,1'-indene]-2,5-dione CAS 1889290-53-2 chemical structure

Description

Based on its molecular formula C11H9BrN2O2, (S)-5'-Bromo-2',3'-dihydrospiro[imidazolidine-4,1'-indene]-2,5-dione 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 281.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(S)-5'-Bromo-2',3'-dihydrospiro[imidazolidine-4,1'-indene]-2,5-dione (CAS 1889290-53-2) is a high-purity analytical reference standard with the molecular formula C11H9BrN2O2 and a molecular weight of 281.11 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.
