Chemical Structure
Description
5-Bromo-2-(4-chlorophenyl)isoindoline-1,3-dione (CAS 82104-73-2), molecular formula C14H7BrClNO2 and molecular weight 336.57 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H7BrClNO2, 5-Bromo-2-(4-chlorophenyl)isoindoline-1,3-dione 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 336.57 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
