CATO supplies 1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 1,3-isobenzofurandione (CAS 61630-88-4), a certified reference material (molecular formula C8Cl4O3C8H4O3C2H6O2, MW 496.07 g/mol) for analytical method development and quality control.
1,3-Isobenzofurandione, 4,5,6,7-tetrachloro-, polymer with 1,2-ethanediol and 1,3-isobenzofurandione (C8Cl4O3C8H4O3C2H6O2) 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. 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.
