Ethyl 4-amino-2-fluoro-5-nitrobenzoate CAS 1219014-07-9

Description

The occurrence of Ethyl 4-amino-2-fluoro-5-nitrobenzoate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 4-amino-2-fluoro-5-nitrobenzoate (CAS 1219014-07-9), a certified reference material (molecular formula C9H9FN2O4, MW 228.18 g/mol) for analytical method development and quality control.

Ethyl 4-amino-2-fluoro-5-nitrobenzoate (C9H9FN2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

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.
