Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 231.26 g/mol gives tert-Butyl (2S,4R)-2-acetyl-4-fluoropyrrolidine-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyl (2S,4R)-2-acetyl-4-fluoropyrrolidine-1-carboxylate (CAS 2348315-76-2) is a high-purity analytical reference standard with the molecular formula C11H18FNO3 and a molecular weight of 231.26 g/mol.
The molecular framework of tert-Butyl (2S,4R)-2-acetyl-4-fluoropyrrolidine-1-carboxylate (C11H18FNO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
