1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol, 2,5-furandione and 3a,4,7,7a-tetrahydro-1,3-isobenzofurandione (CAS 53859-83-9), molecular formula C8Cl4O3C8H8O3C4H2O3C2H6O2 and molecular weight 598.16 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol, 2,5-furandione and 3a,4,7,7a-tetrahydro-1,3-isobenzofurandione (C8Cl4O3C8H8O3C4H2O3C2H6O2) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
