Chemical Structure
Description
CATO supplies 5-bromo-1-[2-(dimethylamino)ethyl]-2,3-dihydro-1H-indole-2,3-dione hydrochloride (CAS 156120-10-4), a certified reference material (molecular formula C12H13BrN2O2HCl, MW 333.61 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H13BrN2O2HCl, 5-bromo-1-[2-(dimethylamino)ethyl]-2,3-dihydro-1H-indole-2,3-dione hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 333.61 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.
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.
