Description
2,2'-(1,4-DIoxo-3,6-diphenylpyrrolo[3,4-c]pyrrole-2,5(1h,4h)-diyl)diacetic acid (CAS 632286-84-1), molecular formula C22H16N2O6 and molecular weight 404.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,2'-(1,4-DIoxo-3,6-diphenylpyrrolo[3,4-c]pyrrole-2,5(1h,4h)-diyl)diacetic acid (C22H16N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 404.37 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).
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.
