2-(2,5-Dioxo-2,5-dihydro-1h-pyrrol-1-yl)-2-phenylacetic acid CAS 777917-71-2

Description

The occurrence of 2-(2,5-Dioxo-2,5-dihydro-1h-pyrrol-1-yl)-2-phenylacetic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(2,5-Dioxo-2,5-dihydro-1h-pyrrol-1-yl)-2-phenylacetic acid (CAS 777917-71-2), a certified reference material (molecular formula C12H9NO4, MW 231.20 g/mol) for analytical method development and quality control.

The molecular framework of 2-(2,5-Dioxo-2,5-dihydro-1h-pyrrol-1-yl)-2-phenylacetic acid (C12H9NO4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
