Chemical Structure
Description
Structurally, (3R,4S)-4-(6-fluorobenzofuran-5-yl)-2-oxopyrrolidine-3-carboxylic acid (C13H10FNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 263.22 g/mol, it falls into the medium-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.
(3R,4S)-4-(6-fluorobenzofuran-5-yl)-2-oxopyrrolidine-3-carboxylic acid (CAS 1784748-02-2) is a high-purity analytical reference standard with the molecular formula C13H10FNO4 and a molecular weight of 263.22 g/mol.
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.
