Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Isobenzofurandione, polymer with 2,5-furandione and 2-methyloxirane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.25 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).
CATO supplies 1,3-Isobenzofurandione, polymer with 2,5-furandione and 2-methyloxirane (CAS 26221-28-3), a certified reference material (molecular formula C8H4O3C4H2O3C3H6O, MW 304.25 g/mol) for analytical method development and quality control.
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 2,5-furandione and 2-methyloxirane 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.
