Chemical Structure

1-(tert-Butyl) 2-methyl (2R,4R)-4-fluoro-2-(methoxymethyl)pyrrolidine-1,2-dicarboxylate CAS 2803283-21-6 chemical structure

Description

Based on its molecular formula C13H22FNO5, 1-(tert-Butyl) 2-methyl (2R,4R)-4-fluoro-2-(methoxymethyl)pyrrolidine-1,2-dicarboxylate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1-(tert-Butyl) 2-methyl (2R,4R)-4-fluoro-2-(methoxymethyl)pyrrolidine-1,2-dicarboxylate (CAS 2803283-21-6), molecular formula C13H22FNO5 and molecular weight 291.32 g/mol, is a CATO reference standard with documented purity and traceability.

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.
