(2S,4S)-4-(2-bromo-4-chlorophenoxy)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid CAS 1354484-82-4 chemical structure

Description

The occurrence of (2S,4S)-4-(2-bromo-4-chlorophenoxy)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S,4S)-4-(2-bromo-4-chlorophenoxy)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid (CAS 1354484-82-4), molecular formula C16H19BrClNO5 and molecular weight 420.68 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H19BrClNO5, (2S,4S)-4-(2-bromo-4-chlorophenoxy)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 420.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
