Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 211.26 g/mol gives 1-Ethyl-3-(5-methyltetrahydrofuran-2-yl)pyrrolidine-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Ethyl-3-(5-methyltetrahydrofuran-2-yl)pyrrolidine-2,5-dione (CAS 575114-75-9) is a high-purity analytical reference standard with the molecular formula C11H17NO3 and a molecular weight of 211.26 g/mol.
The molecular framework of 1-Ethyl-3-(5-methyltetrahydrofuran-2-yl)pyrrolidine-2,5-dione (C11H17NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
