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 (CAS 67815-78-5) is a high-purity analytical reference standard with the molecular formula C8H4O3C6H14O3C4H2O3 and a molecular weight of 380.35 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Isobenzofurandione, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and 2,5-furandione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
