Chemical Structure
Description
3,3'-((Ethane-1,2-diylbis(oxy))bis(4,1-phenylene))bis(pyrrolidine-2,5-dione) (CAS 87367-87-1), molecular formula C22H20N2O6 and molecular weight 408.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,3'-((Ethane-1,2-diylbis(oxy))bis(4,1-phenylene))bis(pyrrolidine-2,5-dione) (C22H20N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 408.40 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.
As a certified reference material (CRM), 3,3'-((Ethane-1,2-diylbis(oxy))bis(4,1-phenylene))bis(pyrrolidine-2,5-dione) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
