Ethyl 2-amino-4-(2,3-dichlorophenyl)thiophene-3-carboxylate CAS 1101067-95-1

Description

Ethyl 2-amino-4-(2,3-dichlorophenyl)thiophene-3-carboxylate (C13H11Cl2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies Ethyl 2-amino-4-(2,3-dichlorophenyl)thiophene-3-carboxylate (CAS 1101067-95-1), a certified reference material (molecular formula C13H11Cl2NO2S, MW 316.20 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.
