Chemical Structure
Description
Based on its molecular formula C13H20O4C8H4O3, 1,3-Isobenzofurandione, polymer with 1,5-pentanediol, bis(2-methyl-2-propenoate) 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 388.42 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).
CATO supplies 1,3-Isobenzofurandione, polymer with 1,5-pentanediol, bis(2-methyl-2-propenoate) (CAS 82339-06-8), a certified reference material (molecular formula C13H20O4C8H4O3, MW 388.42 g/mol) for analytical method development and quality control.
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.
