Chemical Structure
Description
2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)propanoic acid (CAS 62212-14-0) is a high-purity analytical reference standard with the molecular formula C7H7NO4 and a molecular weight of 169.13 g/mol.
2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)propanoic acid (C7H7NO4) 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.
CATO manufactures 2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
