Compared with other compounds in its class, the molecular weight of 456.44 g/mol gives 1,3-Isobenzofurandione, polymer with 2,2-dimethyl-1,3-propanediol, 2,5-furandione and 2,2'-oxybis[ethanol] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,3-Isobenzofurandione, polymer with 2,2-dimethyl-1,3-propanediol, 2,5-furandione and 2,2'-oxybis[ethanol] (CAS 51394-70-8), a certified reference material (molecular formula C8H4O3C4H10O3C5H12O2C4H2O3, MW 456.44 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Isobenzofurandione, polymer with 2,2-dimethyl-1,3-propanediol, 2,5-furandione and 2,2'-oxybis[ethanol] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 456.44 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.
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.
