Chemical Structure
Description
The molecular framework of (R)-2-amino-3-(4-bromothiophen-2-yl)propanoic acid (C7H8BrNO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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-amino-3-(4-bromothiophen-2-yl)propanoic acid (CAS 1269836-26-1) is a high-purity analytical reference standard with the molecular formula C7H8BrNO2S and a molecular weight of 250.11 g/mol.
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.
