Chemical Structure

N,N’-Biphthalimide CAS 4388-29-8 chemical structure

Description

N,N’-Biphthalimide (CAS 4388-29-8) is a high-purity analytical reference standard with the molecular formula C16H8N2O4 and a molecular weight of 292.25 g/mol.

Based on its molecular formula C16H8N2O4, N,N’-Biphthalimide contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 292.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
