Chemical Structure
Description
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.
2-Benzyl 1-(tert-butyl) (2S,4R)-4-(4-bromobenzyl)-5-oxopyrrolidine-1,2-dicarboxylate (CAS 401793-01-9) is a high-purity analytical reference standard with the molecular formula C24H26BrNO5 and a molecular weight of 488.37 g/mol.
2-Benzyl 1-(tert-butyl) (2S,4R)-4-(4-bromobenzyl)-5-oxopyrrolidine-1,2-dicarboxylate (C24H26BrNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
