(Z)-3-(4-Hydroxy-2-oxopent-3-en-1-yl)-1-methylpyrrolidine-2,5-dione CAS 206562-86-9

Description

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.

(Z)-3-(4-Hydroxy-2-oxopent-3-en-1-yl)-1-methylpyrrolidine-2,5-dione (CAS 206562-86-9), molecular formula C10H13NO4 and molecular weight 211.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (Z)-3-(4-Hydroxy-2-oxopent-3-en-1-yl)-1-methylpyrrolidine-2,5-dione (C10H13NO4) is characterized by an amino-acid-derived structure, 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).

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.
