Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3-Acetyl-4-hydroxy-5-oxo-2-phenyl-2,5-dihydro-1H-pyrrol-1-yl)propanoic acid.
3-(3-Acetyl-4-hydroxy-5-oxo-2-phenyl-2,5-dihydro-1H-pyrrol-1-yl)propanoic acid (CAS 371232-66-5), molecular formula C15H15NO5 and molecular weight 289.28 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(3-Acetyl-4-hydroxy-5-oxo-2-phenyl-2,5-dihydro-1H-pyrrol-1-yl)propanoic acid (C15H15NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 289.28 g/mol, it falls into the medium-molecular-weight range. 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 3-(3-Acetyl-4-hydroxy-5-oxo-2-phenyl-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.
