Chemical Structure
Description
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.
1,3-Isobenzofurandione, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and 2,5-furandione, isononanoate (CAS 79770-81-3) is a high-purity analytical reference standard with the molecular formula C9H18O2C8H4O3C6H14O3C4H2O3 and a molecular weight of 538.59 g/mol.
Structurally, 1,3-Isobenzofurandione, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and 2,5-furandione, isononanoate (C9H18O2C8H4O3C6H14O3C4H2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 538.59 g/mol, it falls into the moderately-high-molecular-weight range. 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.
