Chemical Structure
Description
The occurrence of 1,3-Isobenzofurandione, 4,5,6,7-tetrabromo-, polymer with 2,5-furandione and 1,2-propanediol is closely related to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,3-Isobenzofurandione, 4,5,6,7-tetrabromo-, polymer with 2,5-furandione and 1,2-propanediol (CAS 28574-50-7), a certified reference material (molecular formula C8Br4O3C4H2O3C3H8O2, MW 637.85 g/mol) for analytical method development and quality control.
Structurally, 1,3-Isobenzofurandione, 4,5,6,7-tetrabromo-, polymer with 2,5-furandione and 1,2-propanediol (C8Br4O3C4H2O3C3H8O2) contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 637.85 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
