1,1'-((1,3-Phenylenebis(oxy))bis(4,1-phenylene))bis(1H-pyrrole-2,5-dione) CAS 115341-26-9

Description

Structurally, 1,1'-((1,3-Phenylenebis(oxy))bis(4,1-phenylene))bis(1H-pyrrole-2,5-dione) (C26H16N2O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 452.42 g/mol, it falls into the moderately-high-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).

1,1'-((1,3-Phenylenebis(oxy))bis(4,1-phenylene))bis(1H-pyrrole-2,5-dione) (CAS 115341-26-9) is a high-purity analytical reference standard with the molecular formula C26H16N2O6 and a molecular weight of 452.42 g/mol.

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.
