Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Isobenzofurandione, polymer with 2-(hydroxymethyl)-2-methyl-1,3-propanediol, nonanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1,3-Isobenzofurandione, polymer with 2-(hydroxymethyl)-2-methyl-1,3-propanediol, nonanoate (CAS 70289-46-2), molecular formula C14H28O4C8H4O3 and molecular weight 408.49 g/mol, is a CATO reference standard with documented purity and traceability.
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.
