Chemical Structure
Description
2-{2-[(4-bromophenyl)sulfanyl]ethyl}-2,3-dihydro-1H-isoindole-1,3-dione (CAS 269743-56-8), molecular formula C16H12BrNO2S and molecular weight 362.24 g/mol, is a CATO reference standard with documented purity and traceability.
2-{2-[(4-bromophenyl)sulfanyl]ethyl}-2,3-dihydro-1H-isoindole-1,3-dione (C16H12BrNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
