Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-[2-(2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]pentanoic acid.
5-[2-(2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]pentanoic acid (CAS 2773558-47-5), molecular formula C18H18N2O6 and molecular weight 358.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 5-[2-(2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]pentanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
