Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,5-Furandione, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene, (1-methylethenyl)benzene and 3a,4,7,7a-tetrahydro-4,7-methano-1H-indene (CAS 70495-40-8) is a high-purity analytical reference standard with the molecular formula C10H12C9H10C9H8C8H8C4H2O3 and a molecular weight of 568.76 g/mol.
Structurally, 2,5-Furandione, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene, (1-methylethenyl)benzene and 3a,4,7,7a-tetrahydro-4,7-methano-1H-indene (C10H12C9H10C9H8C8H8C4H2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 568.76 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).
As a certified reference material (CRM), 2,5-Furandione, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene, (1-methylethenyl)benzene and 3a,4,7,7a-tetrahydro-4,7-methano-1H-indene 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.
