Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 326.21 g/mol gives 3598AE 438218-48-5 C13H12BrNO2S Ethyl 2-amino-4-(3-bromophenyl)thiophene-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3598AE 438218-48-5 C13H12BrNO2S Ethyl 2-amino-4-(3-bromophenyl)thiophene-3-carboxylate (CAS 438218-48-5), a certified reference material (molecular formula C13H12BrNO2S, MW 326.21 g/mol) for analytical method development and quality control.
The molecular framework of 3598AE 438218-48-5 C13H12BrNO2S Ethyl 2-amino-4-(3-bromophenyl)thiophene-3-carboxylate (C13H12BrNO2S) 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 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).
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.
