5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 2,2'-oxybis[ethanol] and 3a,4,7,7a-tetrahydro-1,3-isobenzofurandione CAS 70942-07-3

Description

The occurrence of 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 2,2'-oxybis[ethanol] and 3a,4,7,7a-tetrahydro-1,3-isobenzofurandione 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.

5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 2,2'-oxybis[ethanol] and 3a,4,7,7a-tetrahydro-1,3-isobenzofurandione (CAS 70942-07-3), molecular formula C9H4O5C8H8O3C4H10O3 and molecular weight 450.40 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H4O5C8H8O3C4H10O3, 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 2,2'-oxybis[ethanol] and 3a,4,7,7a-tetrahydro-1,3-isobenzofurandione contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 450.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
