5-[2-(2,6-dioxo-3-piperidyl)-3-oxo-isoindolin-5-yl]oxypentanal CAS 2591190-72-4

Description

The occurrence of 5-[2-(2,6-dioxo-3-piperidyl)-3-oxo-isoindolin-5-yl]oxypentanal is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-[2-(2,6-dioxo-3-piperidyl)-3-oxo-isoindolin-5-yl]oxypentanal (CAS 2591190-72-4), molecular formula C18H20N2O5 and molecular weight 344.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-[2-(2,6-dioxo-3-piperidyl)-3-oxo-isoindolin-5-yl]oxypentanal (C18H20N2O5) is characterized by a flavonoid core, 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).

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.
