Chemical Structure
Description
Fmoc-2-aminoethylbromide 9-Fluorenylmethyl N-(2-bromoethyl)carbamate 2-(Fmoc-amino)ethyl bromide N-Fmoc-2-bromoethylamine 340187-12-4 (CAS 340187-12-4) is a high-purity analytical reference standard with the molecular formula C17H16BrNO2 and a molecular weight of 346.22 g/mol.
The molecular framework of Fmoc-2-aminoethylbromide 9-Fluorenylmethyl N-(2-bromoethyl)carbamate 2-(Fmoc-amino)ethyl bromide N-Fmoc-2-bromoethylamine 340187-12-4 (C17H16BrNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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.
