5-Ethoxy-1-(4-nitrobenzoyl)pyrrolidin-2-one CAS 119984-32-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Ethoxy-1-(4-nitrobenzoyl)pyrrolidin-2-one.

5-Ethoxy-1-(4-nitrobenzoyl)pyrrolidin-2-one (CAS 119984-32-6) is a high-purity analytical reference standard with the molecular formula C13H14N2O5 and a molecular weight of 278.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Ethoxy-1-(4-nitrobenzoyl)pyrrolidin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.26 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
