Chemical Structure

Ethyl 2-((4-fluoro-3-nitrophenyl)amino)-2-oxoacetate CAS 69066-09-7 chemical structure

Description

As a certified reference material (CRM), Ethyl 2-((4-fluoro-3-nitrophenyl)amino)-2-oxoacetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Ethyl 2-((4-fluoro-3-nitrophenyl)amino)-2-oxoacetate (CAS 69066-09-7) is a high-purity analytical reference standard with the molecular formula C10H9FN2O5 and a molecular weight of 256.19 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 2-((4-fluoro-3-nitrophenyl)amino)-2-oxoacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
