Chemical Structure
Description
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.
(2S,4S)-1-(tert-Butoxycarbonyl)-4-[(1,6-dibromo-2-naphthyl)oxy]-2-pyrrolidinecarboxylic acid (CAS 1354486-43-3), molecular formula C20H21Br2NO5 and molecular weight 515.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, (2S,4S)-1-(tert-Butoxycarbonyl)-4-[(1,6-dibromo-2-naphthyl)oxy]-2-pyrrolidinecarboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 515.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
