2,5-Dioxopyrrolidin-1-yl (2R)-2,5,7,8-tetramethyl-6-((tetrahydro-2H-pyran-2-yl)oxy)chromane-2-carboxylate (CAS 1069137-73-0) is a high-purity analytical reference standard with the molecular formula C23H29NO7 and a molecular weight of 431.48 g/mol.
Structurally, 2,5-Dioxopyrrolidin-1-yl (2R)-2,5,7,8-tetramethyl-6-((tetrahydro-2H-pyran-2-yl)oxy)chromane-2-carboxylate (C23H29NO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 431.48 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
