Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 3a,4,7,7a-tetrahydro-4,7-methano-1H-indene.
CATO supplies 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 3a,4,7,7a-tetrahydro-4,7-methano-1H-indene (CAS 25748-93-0), a certified reference material (molecular formula C8H4O3C10H12C4H2O3C2H6O2, MW 440.45 g/mol) for analytical method development and quality control.
Structurally, 1,3-Isobenzofurandione, polymer with 1,2-ethanediol, 2,5-furandione and 3a,4,7,7a-tetrahydro-4,7-methano-1H-indene (C8H4O3C10H12C4H2O3C2H6O2) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 440.45 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.
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.
