1,3-Isobenzofurandione, 5,5'-[[1,1'-biphenyl]-4,4'-diylbis(oxy)]bis-, polymer with 1,3-isobenzofurandione and 4,4'-sulfonylbis[benzenamine] (CAS 125881-35-8), molecular formula C28H14O8C12H12N2O2SC8H4O3 and molecular weight 874.83 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,3-Isobenzofurandione, 5,5'-[[1,1'-biphenyl]-4,4'-diylbis(oxy)]bis-, polymer with 1,3-isobenzofurandione and 4,4'-sulfonylbis[benzenamine] (C28H14O8C12H12N2O2SC8H4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 35.0, corresponding to approximately 35 ring(s) or double-bond equivalent(s). With a molecular weight of 874.83 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
