Chemical Structure

(Z)-Ethyl 3-((4-fluorophenyl)amino)but-2-enoate CAS 18529-17-4 chemical structure

Description

The occurrence of (Z)-Ethyl 3-((4-fluorophenyl)amino)but-2-enoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(Z)-Ethyl 3-((4-fluorophenyl)amino)but-2-enoate (CAS 18529-17-4), molecular formula C31H28O12 and molecular weight 592.55 g/mol, is a CATO reference standard with documented purity and traceability.

(Z)-Ethyl 3-((4-fluorophenyl)amino)but-2-enoate (C31H28O12) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), (Z)-Ethyl 3-((4-fluorophenyl)amino)but-2-enoate 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.
