1-(Tert-butyl) 2-methyl (2S,4S)-4-(3-bromo-2,5-difluorophenoxy)pyrrolidine-1,2-dicarboxylate CAS 2442510-68-9 chemical structure

Description

The occurrence of 1-(Tert-butyl) 2-methyl (2S,4S)-4-(3-bromo-2,5-difluorophenoxy)pyrrolidine-1,2-dicarboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(Tert-butyl) 2-methyl (2S,4S)-4-(3-bromo-2,5-difluorophenoxy)pyrrolidine-1,2-dicarboxylate (CAS 2442510-68-9) is a high-purity analytical reference standard with the molecular formula C17H20BrF2NO5 and a molecular weight of 436.25 g/mol.

Structurally, 1-(Tert-butyl) 2-methyl (2S,4S)-4-(3-bromo-2,5-difluorophenoxy)pyrrolidine-1,2-dicarboxylate (C17H20BrF2NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 436.25 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
