1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 4-pentenoate CAS 137258-59-4

Description

The molecular framework of 1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 4-pentenoate (C13H11NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 4-pentenoate (CAS 137258-59-4) is a high-purity analytical reference standard with the molecular formula C13H11NO4 and a molecular weight of 245.23 g/mol.

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.
