3-([1,1'-Biphenyl]-4-yl)-4-hydroxy-1H-pyrrole-2,5-dione (CAS 77529-41-0), molecular formula C16H11NO3 and molecular weight 265.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-([1,1'-Biphenyl]-4-yl)-4-hydroxy-1H-pyrrole-2,5-dione (C16H11NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
