Chemical Structure
Description
The molecular framework of Ethyl 1-amino-5-bromo-4-fluoro-2,3-dihydro-1H-indene-1-carboxylate hydrochloride (C12H13BrFNO2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies Ethyl 1-amino-5-bromo-4-fluoro-2,3-dihydro-1H-indene-1-carboxylate hydrochloride (CAS 2089649-44-3), a certified reference material (molecular formula C12H13BrFNO2HCl, MW 338.60 g/mol) for analytical method development and quality control.
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.
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.
