Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-2-((4-nitrobenzylidene)amino)isoindoline-1,3-dione.
(E)-2-((4-nitrobenzylidene)amino)isoindoline-1,3-dione (CAS 32387-08-9) is a high-purity analytical reference standard with the molecular formula C15H9N3O4 and a molecular weight of 295.25 g/mol.
(E)-2-((4-nitrobenzylidene)amino)isoindoline-1,3-dione (C15H9N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
