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.
2-(phenylselanyl)isoindoline-1,3-dione 71098-88-9 N-(Phenylseleno)phthalimide (CAS 71098-88-9) is a high-purity analytical reference standard with the molecular formula C14H21NO2Se and a molecular weight of 314.28 g/mol.
2-(phenylselanyl)isoindoline-1,3-dione 71098-88-9 N-(Phenylseleno)phthalimide (C14H21NO2Se) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
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.
