Description
Compared with other compounds in its class, the molecular weight of 414.36 g/mol gives 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 2,2'-oxybis[ethanol] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 2,2'-oxybis[ethanol] (CAS 28679-80-3), molecular formula C8H4O3C4H10O3C4H2O3C2H6O2 and molecular weight 414.36 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 2,2'-oxybis[ethanol] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 414.36 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 2,2'-oxybis[ethanol] 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.
