Description
CATO supplies 2,5-Dioxopyrrolidin-1-yl 4-(4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)phenyl)butanoate (CAS 79886-55-8), a certified reference material (molecular formula C18H16N2O6, MW 356.33 g/mol) for analytical method development and quality control.
Structurally, 2,5-Dioxopyrrolidin-1-yl 4-(4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)phenyl)butanoate (C18H16N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 356.33 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.
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.
