5-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)pentanoic Acid CAS 57078-99-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)pentanoic Acid.

5-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)pentanoic Acid (CAS 57078-99-6) is a high-purity analytical reference standard with the molecular formula C9H11NO4 and a molecular weight of 197.19 g/mol.

5-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)pentanoic Acid (C9H11NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
