Description

Structurally, 4,4',6-Trimethoxy-6'-methyl-3'-grisen-2',3-dione 4,4',6-Trimethoxy-6'-methyl-spiro[benzofuran-2(3H),1'-[3]cyclohexene]-2',3-dione 56783-97-2 (C17H18O6) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 318.32 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).

CATO supplies 4,4',6-Trimethoxy-6'-methyl-3'-grisen-2',3-dione 4,4',6-Trimethoxy-6'-methyl-spiro[benzofuran-2(3H),1'-[3]cyclohexene]-2',3-dione 56783-97-2 (CAS 56783-97-2), a certified reference material (molecular formula C17H18O6, MW 318.32 g/mol) for analytical method development and quality control.

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.
