Chemical Structure
Description
The molecular framework of (R)-2-((5-bromothiophen-2-yl)methyl)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid (C15H20BrNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(R)-2-((5-bromothiophen-2-yl)methyl)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid (CAS 959578-36-0) is a high-purity analytical reference standard with the molecular formula C15H20BrNO4S and a molecular weight of 390.29 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
