61128-46-9 1,3-Isobenzofurandione, 5,5'-((1-methylethylidene)bis(4,1-phenyleneoxy))bis-, polymer with 1,3-benzenediamine CAS 61128-46-9

Description

As a certified reference material (CRM), 61128-46-9 1,3-Isobenzofurandione, 5,5'-((1-methylethylidene)bis(4,1-phenyleneoxy))bis-, polymer with 1,3-benzenediamine 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.

61128-46-9 1,3-Isobenzofurandione, 5,5'-((1-methylethylidene)bis(4,1-phenyleneoxy))bis-, polymer with 1,3-benzenediamine (CAS 61128-46-9), molecular formula C31H20O8C6H8N2 and molecular weight 628.64 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 61128-46-9 1,3-Isobenzofurandione, 5,5'-((1-methylethylidene)bis(4,1-phenyleneoxy))bis-, polymer with 1,3-benzenediamine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 628.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
