Chemical Structure
Description
The occurrence of 1,3-Isobenzofurandione, polymer with 2,2-dimethyl-1,3-propanediol, 1,2-ethanediol and 2,5-furandione is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,3-Isobenzofurandione, polymer with 2,2-dimethyl-1,3-propanediol, 1,2-ethanediol and 2,5-furandione (CAS 42133-45-9), a certified reference material (molecular formula C8H4O3C5H12O2C4H2O3C2H6O2, MW 412.39 g/mol) for analytical method development and quality control.
1,3-Isobenzofurandione, polymer with 2,2-dimethyl-1,3-propanediol, 1,2-ethanediol and 2,5-furandione (C8H4O3C5H12O2C4H2O3C2H6O2) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
